Faggot, do you know where the fuck you are?

Hey there! I'm a 21-year-old gal from the US, a little on the curvy side, and I absolutely love taking charge in those sizzling online chats. There's just something thrilling about pushing boundaries and seeing how far I can tease someone while we both have a blast. I'm always in the mood for some fun (total wild child vibes!), but I do struggle with social anxiety, so meeting up isn't really my scene. That's why I'm all about those flirty convos; it's so much easier for me! If you're interested in some steamy chat, add me on 4e-m-a-q-u-o-n-x (just make sure to remove the spaces and dashes). Can't wait to connect with some cool people!

So, one coin landing heads is already stabilished.
The event is only the second coin landing heads or tails, so 1/2.

Whoever says 1/3 is retarded.
>>937975580
HT or TH is the same thing it doesn't matter if the first or the second coin landed on heads. A coin, any of them, is heads. This is all the info you need.

No Anon, it's asking about the second coin.
The first is a ALREADY heads.
Stop being fucking stupid. It's 50% because the first heads doesn't change the second coin.

>>937981555
Yes it's a conditional, you stupid fuck i.e.
what is the probability of event A given event B

I'm sorry for being mean to you. It's not your fault you are a dumbass.

Wrong. Reread the question moron,

>>937981786
It's not a condition if the coin is heads.

>>937981808
I did.
If you were right, it would state that the first coin could be head or tails.
No reread it Anon.
Does it state that?
No.
So it's 50% because the first heads doesn't change outcome.

>>937981692
It wouldn't be 1/3 because we are excluding the other circumstances altogether and only asking about the probability based on a set of defined circumstances. We would ignore altogether any instances where the first coin does not land on heads, meaning we are basically only flipping one coin and measuring only in the instance the first circumstance is filled.

>>937982083

>>937982059
Because if you flipped and it was tails then it fails to satisfy the circumstances the question is based on altogether, meaning you're not even fulfilling the initial values of the prompt. It doesn't actually matter which is which, but in any instances where the first one is tails, flipping the next coin is pointless because you're not measuring inside the given values.

>>937982126

This is logically equivalent to stating "If two coins are flipped the first can't be heads".
>>937982159
"Two coins are flipped. What is the probability that both coins land heads if at least one coin lands heads" = the probability of two coins being heads given that one coin is heads = (HH) within the set of (HH HT TH) within the set of (HH HT TH TT)

>>937975456 (OP)
I don't think this is a mathematical constant. There are too many variables that go into a simple coin flip, such as number of turns, height, where it was flicked, where it lands etc... you can say 1/3 but if you try it and poll the results over a 1000 flips I predict it will be quite different and not at all constant.

Otherwise the problem would state the first flip is what's or tails, what's the probability the second is heads.

With the context given and the premise that one of the coins always lands heads, only rational thought can lead to think that the coins are both sides heads, or the coins are loaded. It is 100% heads on the other coin

>>937982323
Are you from a country where one coin always lands heads? Because either the premise is impossible or the chance of the other being heads is 100% then.

Poll real world data and get back to us how it goes. Shit, do 100 flips and plot the data. You made your presumption, now prove it.

LOL dumbass

>>937975456 (OP)
The condition "at least one coin lands on heads" does not specify that the first coin is heads. Instead, it means that at least one of the two coins (first, second, or both) is heads.

wow this thread is a massive cluster fuck. anyways, I thought it was 50% at first because I interpreted it as one coin being flipped first and then being established as heads before the second coin is flipped. but if both coins were flipped at the same time, it would be 1/3 probability for both to land on heads if at least one of the coins has to land on heads, which removes the tails tails option entirely.

>>937981171
>The event is only the second coin landing heads or tails, so 1/2.
that would be a valid observation if the question were "One coin is flipped. It landed on heads. When the second coin is flipped, what are the odds that both coins will be heads?"
but that's not the question that was asked
in the question in OP, the coins are already being flipped and you're given a piece of information about one of the coins, but not any particular coin
there is no first or second coin

>>937983384
>but if both coins were flipped at the same time, it would be 1/3 probability

it doesn't matter if they are flipped at the same time you stupid fuck. The answer is still 1/3 when at least 1 coin lands heads.

That was just to help clarify the lack of guarantee of the first coin landing heads and then the second one being flipped as people are trying to eliminate the Tails and then Heads option in addition to the Tails/Tails option as well, you obvious double-nigger.

>>937985202
Is it possible to do this in your head? It seems like it would take up too much working memory (unlike the coin flip).
ps NTA, but I accept 1/11.

>>937986090
sure, if you start to imagine a list of possibilities:
1 1
1 2
1 3
1 4

etc., you can realize that there are six possibilities where at least one die is 4, those being
4 1
4 2
...
4 6

and an additional five possibilities in the form of 1 4, 2 4, 3 4, 5 4, and 6 4, for a total of 11 possibilities where at least one die is 4

but there's only one of these where both dice are 4 (i.e. 4 4), so it's 1 possibility out of 11, making the odds 1/11

so the key is to not try to keep all 36 combinations in your head simultaneously and count them, but to recognize the pattern

So ill lay it out for those saying it is 1/2 (its not). There are 2 coins to flip. If you flip the first coin and it lands on tails, you stop, because the conditions are satisfied. If it lands heads, you must flip again, because the conditions are not yet satisfied, and you must flip again. There is <50% chance that heads is flipped twice.

>>937975456 (OP)
well based on the way the question is asked, the answer is 1/2 because the first coin is predestined to land on heads which means it's 100% going to be heads.

>if at least 1 coin lands on heads.
so under the premise at least one coin will always be heads, so the probability that both land on heads is 1/2

If the question was
>two coins are flipped at the same time, what is the probability that both coins land on heads
then the answer would be 1/4

I'll prove it mathematically
There are 2 coins with 2 faces each and 2 distinct subsets (1 and 0)
4 potential configurations
1 1
0 0
1 0
0 1

but 1 0 = 0 1

so 3 distinct configurations

BUT
based on the premise of the question one subset will always be presumed to land on heads
so the configuration becomes
1 0
or
1 1

The probability of the second coin landing on heads if one of the two is presumed to be heads is 50%

>>937995208
nope
how does it feel to be a midwit?
i bet it feels good
most midwits are quite self-satisfied

>>937995635
Sorry to tell you this but the answer absolutely has to be 1/2 because of the way the question is framed.
>What is the probability that both coins will be heads if one coin lands on heads

This puts both coins into a superpositional state until collapsing into the final resting state on the plane where they land their configuration can only be
Heads Heads
Tails Heads
Heads Tails

But because one coin is predestined to be heads based on the premise of the question, "if one coin lands on heads" it therefore means that the final configuration is irrelevant whether that is:
>heads tails
or
>tails heads.

These are interchangeable because one coin WILL be heads and this is just the superposition collapsing upon observation of the final resting state

So the remaining coin which is unbounded by the deterministic presupposition of the question itself has it's original probability and the final probability of both coins landing on heads if one MUST land on heads is 50%

If you don't believe me ask chatGPT or something else to run the actual math for you.
