Let's see how smart /b/ is.

>>937533824 (OP)
50%
The final box is irrelevant.
So it's basically a choice between Box 1 and Box 2.

I made this image years ago lol. Glad to see some anons are still using it for shits and giggles.

The correct answer is 2/3 due to the fact that the first ball pulled from the box was gold, meaning you are twice as likely to have the box with 2 gold balls.

>>937533976
This guy is a fucking idiot.

Let the games begin.

>>937533976
Think harder

>>937533824 (OP)
30% because only one box still has a gold ball

>>937534114
Holy shit, you made it? These were some of my favorite threads, a long with the two coins ones. Had so much fun watching retards try to argue their positions kek.

>>937533824 (OP)
yes indeed. yes, indeed!

>>937534114
So now the order matters.

>>937533824 (OP)
lower

>>937534187
Yeah that was the whole point. Calling the 50% people retards. I have entire folders dedicated to trolling those simpletons. I made the 2 coins one too.

Posted it yesterday for the first time in over a year probably. It's time to make a comeback. Strap in and buckle up.

>>937533824 (OP)
Reminder that gold balls is slang for testicles.
OP is a fag for wanting you to touch his balls.

>>937534263
You'll have to expand on what you mean there, bucko, and explain what you think the answer is and why.

>>937534307
Did you make the portals physics one too?

>>937534307
Imagine being so pathetic that you can only gain enjoyment from shitty word games where you fantasize about other guys touching your balls.

>>937534441
No

>>937534494
U mad bro?

>>937534494
>word games

>>937533824 (OP)
66.6%? i think because of the conditional probability that you must be in box a or b, and 1 ball is known. so a 2/3's shot

>>937533824 (OP)
2/3. Several ways to explain it but the simplest explanation is that you're just more likely to have picked from the first box than the second.

>>937535789
The simplest explanation is that you are wrong and OP will change the answer depending on how the thread is going.

>>937535901
He can play games and fool people. But he cant change the truth. It's 2/3 and it can be demonstrated as such

>>937533976

Literally this.

If I missed the gold one, the second time that I pick, then my odds of 100% of getting a gold drop by the sampling space ratio of which there is, 2 probabilities remaining. as I have already selected a box with a gold ball in it.. there are only two possible probable outcomes that fit the solution of my chances of getting a golden ball.

Either I get a gold ball, or I don't.

I pick 1x more gold balls = 100% of that box containing gold balls.

If I pick 1xgold 1xgrey than 50% of the box has the possible chance of a gold ball.

Because the question is asking us, to ascertain with a certainty, of how many possible outcomes of selecting the second ball from your random box is going to be gold, therefore the probability of getting a gold ball is either 100% (both balls are gold in the box) or 50% where 1 ball is grey. We can rule out the third box, by default, as one golden ball has already been retrieved. So in summation there are only 2 possibilities out of 100%.
100%/2=50%

>The correct answer is 2/3 due to the fact that the first ball pulled from the box was gold, meaning you are twice as likely to have the box with 2 gold balls.
could you actually explain this because you just assert that you are twice as likely to have the box with 2 gold balls. twice as likely compared to what? show your work nigger.

having a statistics education doesn't make you smart. nor does lacking one make you stupid. making deliberate gotchas to make yourself feel superior does make you gay, though.

>>937534114
If you'd want to state 2/3 ergo 75% chance of selecting golden balls in the first place, then you would be assuming that both boxes are being interpreted as 1 attempt each. As one attempt has been achieved you reach in again for another ball from either of the 2 certain boxes that contain a golden ball. You either have 100% in one or 50% in the other as the margin of sampling space is 2 and one has already been made in your favour of collecting a golden ball.. if you hadn't made that selection yet & you wanted to get the common probability of what your direct chances of a golden ball out of 6balls in 3 boxes with 1 box having 100% chance the other one 50% with the final box containing 0% chance then you are left with 1 attempt out of 3 samples with a combination of 6 selections. Which is 1/3 or 33% chance of selecting any with a golden ball so you're still wrong, anon.

>>937537225
not him but pic related is the best way to visualize it

>>937537084
Imagine writing this much just to be wrong KEK

>>937537618
You mean there is 2/3 of a chance that the box you have contains a gold after selecting a gold from a box that is at random. You either have a chance or don't when you pick 2 out of 1 box. The box has already been selected at this point & also has one gold ball removed from it. So currently when you are selecting it's totality of probabables with the total of selections of 1 box and also 1 ball than it's 75% likely that you could pull this off at any point in time. however at the point in question, there is only a 50% chance you can select a golden ball anymore as 1 box either does or does not have a golden ball remaining within it as you have already picked a box and picked a ball at random

>>937537879
Smh

>>937538025
The question isnt. What are the chances you choose box 1 or 2? Its, what are the chances you chose box 1 GIVEN you selected 1 box already and have pulled a gold ball out. The condition changes the math

>>937538208

>what is the probability of the next ball, from the same box?

Obstufication from your viewpoint, surely

>>937533824 (OP)
1/2

>>937537618

Why are people posting these probability threads and then gaslighting against the correct answer which is 1/2?

>>937537225
if the only info you have is that the ball is gold, then there is a 2/3rds chance it was in the box with two gold boxes.

>>937539162
It isnt

What if we add more colors than just gold and silver?

First box with red and green
Second box with green and blue
Third box with blue and red

On first pick you get a red ball, what are the chances of having a blue ball?

>>937536615
No, because he words his problems in a way that multiple interpretations can be possible. There are multiple true answers.

>>937544751
It's a well known problem with a well known answer. Even the wikipedia page doesnt have worded much differently than the way OP did it. All the interpretations that lead you to a wrong answer require you to add or remove things, for example one way to justify 50% is by ignoring "random"
