50%, it's just like having one coin then.

P(A|B) = P(A n B) / P(B)

= (1/4)/(3/4) = 1/3

We're estimating. The probability that a coin flip will be heads is not 1/2 either, but we'll still use that value.

Not that anon, but the answer is 1/3.

flip 2 coins. 4 equally probable outcomes

HH
HT
TH
TT

At least 1 coin landed heads, eliminating TT outcome, leaving 3.

HH

HH is 1 of those 3.

You didn't eliminate the TT chance simply because you cant eliminate anything from happening
Think it like this
You said you got TT imagine that the next time you get TH and then HH and then HT so are you Implying that since you eliminate all four of them now the coins will stay in the air because they ran out of options?
Your logics it's right it probably works in closed systems but this time each coin it's a different system they're not act like if they were together

They're not the same. They are two separate permutations, each of which is equally likely to occur.

Both contain at least 1 heads coin, thus satisfying the condition.

HH
HT
TH

are all valid and equally probable outcomes.

1/3

What are you talking about?

TT is eliminated because the question TELLS US that at least 1 coin landed heads.

If at least 1 coin out of 2 landed heads, tehn both coins CANNOT be TT from that point forward.

This is called CONDITIONAL probability.

What is the probability that both coins landed heads given the CONDITION that at least one coin landed heads.

Answer = 1/3

See Bayes' Theorem in this anon's post here >>684954825

3/4 or 75%

And what kind of coins are those in the picture?

TT is not included in the data. It specifies "given that at least one of them landed on heads" While there are four possible outcomes, only three are considered for this. The other 25% of the data doesn't meet the requirement for inclusion in the analysis

>>684954376
it depends on the mechanism by which you guarantee that ofc.

If you turn one coin in the event of two tails, the chance is 25%,

If you turn one coin to heads whatever happens to the other, the chance is 50%

>>684954376
Straight from college discrete math, counting and probability.
Each flip is a separate (discrete) event. While the overall outcome, into infinity, will average 50-50, no discrete outcome will effect any other discrete outcome.
The answer is 50-50.

Kill yourself.

>>684955918
In our case they are THE same permutation. One coin is always H; therefore the "H" in HT & TH is the for the same coin, the one that is always H

>>684956292
This. You're just throwing out TT data. Your basically flipping one coin

>In our case they are THE same permutation.

No, they are not.

Think of it like this:

Take two different coins. Let's say, a penny, and a quarter. Each coin has a 50% chance of landing either heads or tails. You flip both coins. What are the possible outcomes? Well, let's see:

penny = heads & quarter = heads
penny = heads & quarter = tails
penny = tails & quarter = heads
penny = tails & quarter = tails

4 possible outcomes. Each of them equally likely to occur (25% or 1/4)

Now, surely we can all see how the results,
penny = heads & quarter = tails
and
penny = tails & quarter = heads
are different, right? Surely you can see how these are two distinct, separate and equally probable outcomes, yes?

Answer is 1/3

You're not flipping one coin.

Pic Related: Simulation shows 1/3 is correct

>>684954376
Given that one lands on heads, means there's only 1 coin which's outcome is deciding. There are only two options; heads or tails. So there is 50% chance.

>>684956952
>Given that one lands on heads, means there's only 1 coin which's outcome is deciding.

But that's wrong.

2 coins were flipped. At least 1 landed heads. There are 3 equally probable ways to get at least 1 heads

HH
HT
TH

HH is 1 of those 3

1/3

>>684957100
That actualy makes sense.

I was assuming it would be either
HH
HT

But that was assuming that the first coin would always be heads.

>>684956952
But the question specifically asks for the probability that both coins landed heads, not just the one remaining coin.
