No, I won't give you the answer.

BUT...if he flips three coins, could you list all the possible outcomes?

How many possible outcomes are there?

How many consist of two tails and one head?

What is the probability of getting two tails and one heads? Remember that the probability is (number of successful outcomes) / (total number of possible outcomes)
