That reminds me of the doctor that told me i needed a triple bypass operation. He said "There are three main arteries on your heart and four of them are blocked!" But they only did a triple operation so did they leave one of them blocked?

Every coin had a 0.5 probability for heads and 0.5 for tails. No matter how many coins there are, each coin has the same probability distribution.
5 independent tosses produce 5 independent results. All 5 results could be tails, all 5 results could be heads, there could be a mix, the results become a one sided coin, there is no other side.

Why are you stuck on 5? The probability is 0.5 regardless of the number of coins.

Not meaning to be rude about it but is English not your first language? I don't think I said anything about the chance being a range. The odds of heads in your original question as everybody appears to have understood it are 1 out of 2. The odds of a single head as in your revised question is 5 out of 32. Neither is a range.

Your changing the context of the question to something different than the question in discussion. The odds of guessing the third flip was heads or tails is 1/2 but completely unrelated tot he question at hand,

your choice is out of 5 yes?

not out of 2.

You seem to be getting lost and going off track

1 heads or two heads, or 3 heads , or 4 heads, or 5 heads, is a range out of 5.

Ok , the maths would be to show exactly 1 heads or tails
1/2*(1/2)^4*5=0.15625
And you agree the chance of choosing a result is unknown.

No, the chance isn't unknown... you just calculated it...

What is your chance of an ace choosing from the result?

I'd answer but at this point I'm pretty sure you aren't asking what you think you've asked so why bother?

No, but let's move on.

Thank you, the flip is before the results we are only using the results, So you agree the chance could be a range.

I'm quite sure he does not agree with that.
