whats the probability?

i flip a coin 10 times.

the desired outcome is 9 heads and one tail. the results may come in any order.

winner gets the coin.

10*.5^10 = 1/102.4

Thanks, Beer. I knew you were the only one smart enough on 2+2 to solve this problem. Everyone else here was just avoiding it because they didnt know.

The original post said "a coin", not "a fair coin." Where'd that .5^10 come from?

Online coin flipping is rigged, man.

Nine heads and one tail, I don't care which order they come in -- I'm going to be exhausted. Keep the coin.
