woodrow73 · Answer

you're looking for a combination, not a permutation.  So by finding how many different combinations there are, you can find the probability of 1 head 2 tails coming up.  Note; that  -heads-tails-tails    and  tails-heads-tails  are only 1 combination, not 2.

Yep, so that's your answer. @surryyy

@starrhazel123 You're correct, but you have to lead people to the answer and not give it to them.
