when you picked a door to begin with, you only had a 1/3 chance of being right
when the host reveals a goat, the other door is always a 1/2 chance of being right while the door you started with remains still a 1/3 chance of being right

The only funky thing with the three doors version is that 1/3 is still decently high odds if you stick with your choice. Mathematically switching is better odds, but you just never know.
Think that's what trips people up.

I know you're hung up on this, but it's better to switch. I did discrete maths at uni and I had a discussion about this same problem with my teacher. And he initially thought that remaining with your original choice is fine because it wouldn't make a difference. Then when he conducted this experiment with his wife, he soon realized its better to switch. I forgot why though. Which really annoys me because it opened my mind. Anyway, I'm not calling you stupid. I understand why you think its 50/50.

Basically the idea is that your first pick was made at a time when you had a 33% chance of guessing right, but switching the second time has the 'strength' of a 50% shot.

The real problem is that 1/3 are still really good odds. Not switching in a real-world version is perfectly viable, even if not statistically supported.

The door the host picks isn't bound by probability at all because he knows where the goats are and will always reveal one. Look at it this way: you had a 2/3 chance of picking one of the two goats at first. Since the host will always reveals a goat as well, that only leaves the car behind the remaining door, which is what you're being asked if you want to switch. Of course, you could have gotten "lucky"; the other 1/3 chance is that you picked the car from the start anyway. It's not guaranteed that you picked a goat at first, just more likely since there's twice as many.

It doesn't need a proof. When you first pick it has 1/3 chance.
Yes, after a door was opened both doors have 50/50 chance as an independent event but you have advantage of approaching this problem as not an independent event because of the old info.
If you're not trolling right and really wan to try to this with 10 pieces of paper >>712722814 You will quickly find out that switching is always preferable.

There are 100 doors. You pick door one and it has a 99% chance of having a goat.
He opens 98 other doors, revealing a goat behind all of them.
He will NEVER pick a door with the car and he'll NEVER pick your door.
So since Anons don't intuitively understand it how people are explaining, the odds of you picking the right door are 1% but for Monty he'll never pick the door with the car 100% of the time.
By picking the door you didn't pick you're betting your initial pick was wrong, which 99% of the time it is.
It is not 50/50, maybe in an ethereal sense.

For some reason three doors throws off a lot of people because the initial step of selecting a door before the host eliminates a door influences the probability of the final choice, and that's a logical leap if you only view it as a static 50/50 choice at the end. I think you'd have less people being retarded about it if you used something like ten doors as an example instead of three because more easily illustrates how switching improves your odds.

Let me try and explain it again, simple but thorough. This is from the perspective of someone who has no math skills, just someone who gets it. Once you get it, it will fully make sense too. It's NOT about how many doors are left to pick between, it's entirely about how slim your chance of being correct was in the first place and how much better the chance is afterwards.

You've probably been told before to imagine instead that there were 100 doors, with 99 goats and 1 prize. But let's go through this again becuase it really does help you understand it better. If you had to pick one of these 100 doors, you would only have a 1/100 chance of being correct. THAT'S what's important here, the first intitial choice and how bad the chance of this being correct is. Next, the host deletes 98 other doors, all of which contain goats, and leaves only one other door, and the host knows for sure there is either a prize behind your door or the other door he left. Now the chances of the prize being behind the door he left IS 1/2, but the chances of the prize behind your door REMAINS 1/100. It doesn't magically become 1/2 just because the host revealed which other doors had goats behind them. Really think about this.

Now imagine doing this with 50 doors. It's the same. The door you initially picked has only a 1/50 chance of being correct, the door he leaves after deleting 48 goat doors always has a 1/2 chance of being correct. Imagine this with 25 doors. The door you initially picked only has a 1/25 chance of being correct, the door he leaves has a 1/2 chance.

This works all the way down to 3 doors. The door you initially picked only had a 1/3 chance of being correct, but the door he leaves has a 1/2 chance of being correct. It's NOT about how many doors are left remaining, it's about how poor your chances were when you made your first choice.

If someone had 100 apples in front of you and told you 99 were poisoned after you took one to grab and removed 98 of the ones left would you switch or not. Do you think they specifically chose the one that was left (happens 99% of the time) or it was random (only happens if you pick the non poison apple yourself)
Would you switch

Because the host knows which door has the prize, and after you make your choice, it's his job to elimate every single door from except for two, making sure one of them has the prize behind it. Chances are very very high that you picked a goat, so the other door he chooses to leave is probably the prize. But if in a 1/00 chance you actually picked the prize, then one of the other doors he leaves is just one of the 99 goats.

I was wrong by the way, everything I said was right but the probabilities of the other door actually having the prize are even higher than I said because as I said I'm not a math guy. In the 100 door example, your initial picks chance of being the prize is 1/100, but the other doors chance of being correct that the host leaves is way way way way higher than 1/2, it's actually 99/100. Same for the 50 door example, the other door's chance isn't 1/2 it's actually 49/50, all the way to the 3 door example, where the chance of other door being correct is 2/3.

An easier way to visualize this is to use the concept that all probablities must sum to 1. For instance, say that the probability of rain is 60% and the probably of it not raining is 40%. 0.6+0.4=1. For the Monty door problem the first door has a 1/3 chance of course. In fact each door has that initially. But when you open a door then the probability of the car being behind the opened door is now 0. But the probabilities still have to sum to 1 so the other door will have to have a 2/3 chance. You can use software to simulate this and exaggerate it too. Like have 1000 doors and open up most of them.

There is a difference between picking fresh between two doors and CHANGING your first pick. Your first pick between 3 doors was more likely to be incorrect, so switching after the other wrong option is eliminated is optimal. Picking once between 2 doors without knowing about the first pick is a 50/50 obviously. Which is worse odds for you than switching after picking from 3.

The equation doesn't change, this is what people don't get. Nothing changes, you're just given more information and asked if you would like to switch based on this information. The equation only changes if the prize location is then scrambled between the remaining doors at random after the host reveals a goat, but it doesn't. Everything remains as it was.

The door that is opened to reveal a goat depends on the door that you have selected 2/3 of the time, because when you first select a door with a goat, the game host will not open that door to reveal that goat, but will instead open the other door that has another goat. Therefore, your first selection is statistically likely to affect the odds of the second selection.

4+2 = 5+1
4 + 0 +2 = 5 + 0 + 1 [neutral element of addition]
4 + 2 + (1 - 1) = 5 + (1 - 1) + 1 [definition of neutral element: 0 = a + a for every a in real]
4 + (2 - 1) + 1 = (5 - 1) + 1 + 1 [apply commutative and associative properties]
4 + 1 + 1 = 4 + 1 + 1 [perform subtraction]
both sides show the exact operations and operands so it's done

It's easier to think of the problem as playing cards, rather than goats and doors.
>There is a deck with an arbitrary number of cards (at least 3).
>There is a single winning card.
>You get to add one mystery card to your hand. The host meanwhile adds all the other cards in the deck to his hand.
Is it more likely the winning card exists in your or the host's hand?

In a typical Monty Hall problem the host's hand would have two cards, whereas you'd have one. The host's hand has a 2/3 chance of containing the winning card. Your hand has a 1/3 chance. The host's hand becomes more and more powerful the more cards you add into the original deck.

Because 3 doors for a 1/3 chance means that your odds are still pretty good and it's viable not to change. With 10 doors it becomes more understandable, same with 100.
With 100 doors, not switching means you're convinced you guessed the right door on the first try, out of a hundred doors presented to you.

Alright. instead of thinking of this problem in terms of goats, cars, and shady game show hosts, we should think about it in a way that makes more sense.

Okay, imagine you're in some fucking.... Zelda dungeon or something, I don't know. now, imagine you're in a checkerboard room, which is, let's say, 4x4, meaning it has 16 squares to work with. You're waltzing through, and all of a sudden, a trap: 14 of the tiles collapse into a bottomless pit, leaving only two tiles remaining.
Doesn't it seem like chance that those 14 tiles fell, and two of them didn't? Maybe you should start worrying why the only other tile there is still standing.

Okay, not the most airtight analogy, but you get the point.

It doesn't even matter if he opens the door before you switch or not. He's asking if you want the choice between one door or two (he'll open one of them for you).

The problem with this is that when you are given the new situation it switches to a 50/50 chance between two doors. This is all that matters to normal people.
Snooty statistics teachers still refer to the entire math problem regardless of changed context even though that doesn't matter anymore. All they care about is the numbers. They're the exact same kind of nerds who do those DPS videos for shooter games where the math is impractical and not always accurate to the situation.
Yes, your simulations that account for the goat'd door will work more if you switch. No that literally doesn't matter.

Add all numbers on both sides of the equation (4+2+5+1 = 12)
Subtract the left side of the equation from that total (12-4-2=6)
Subtract the right side of the equation from the original total (12-5-1=6)
Because the answer is 6 in both, each side of the equation must have an equal value and the statement is indeed true.

The host never picks the car. Before you pick your door the car has a 66% chance of being in one of the other doors, but if it's in one of those doors then switching to another door becomes 100% of that 66%, because the option that isn't your door OR the car goes away. It's 33% the car is behind your door, and if it isn't then switching guarantees the car.

The point of the question is that you are allowed to do literally anything to the equation except literally write 6 = 6. There are countless ways to explain it based on solid mathematical fundaments and your job is to use those and show that both sides are in fact equal by using them.

The presented problem is inherently incorrect because if you were choosing a box/bsll at random, then you wouldn't always pull a gold ball. As the problem currently is presented, the double silver box does not exist. As such the odds are 50%. If the question was worded properly then the odds would be 1/3.

The simplest way to put it is this.
At the beginning you have a higher chance of picking a goat first; Since there are 2/3 doors with a goat.
That means MORE OFTEN THAN NOT you have picked a door with a goat behind it starting off.

So when the host eliminates a door he knows a goat is behind you STILL HAVE A BIGGER CHANCE TO HAVE ALREADY PICKED A GOAT behind your door.
So if the host eliminated a goat and you more than likely already have the other goat behind your initial pick, what is left? The car.

The entire "puzzle" hinges on a persons' pride about not changing their mind under pressure.
That's why the show got cancelled because people figured it's statistically better to just switch every time.

Because there's an equal sign, which means that both sides are the same. If they aren't then someone made a mistake or the teacher is a faggot.

that's only true if you bring in a third party who doesn't know which door you originally picked to choose for you

The question fundamentally does not change if you rewrite the question to be "incorrect" though.
>4+2 = 5+2
"Can you prove" is the critical operator with the condition being "without solving both sides of the equation"
You need to have a triple-digit IQ in order to participate in these kinds of questions.

had i not had breakfast this morning id imagine id feel somewhat hungry currently and perhaps somewhat irritable due to that.
However its fathers day so my lovely wife and wonderful children did in fact serve me breakfast in bed, thusly no such breakfast-less condition has presented itself.

Look, if you think that the car really is behind the door that you would pick first, by picking a different door on the first round you have a 50% chance of being proven incorrect about that initial assumption. If you think that the car is behind door 1, and the presenter shows that a goat is behind door 1 instead, you gain a second try at guessing, which doubles your chances. The presenter won't show you what's behind the door you pick first, so to have him have a chance of showing what's behind the door that you think the car is behind, you should pick a different door on the first round, and then switch.

It's said that your choice has 1/3 probability at the start. But if you know that the host will open a wrong door once you pick, then one wrong choice is immediately removed before you've chosen. So you're actually picking with a 1/2 probability.
