Okay, here we have this:

Considering the provided information, we are going to calculate the requested proability, so we obtain the following:

So what we will do is calculate the probability of each simple event separately and multiply them to find the probability that all three occur, then we have:

Probability of getting 1 head and 2 tails when flipping a coin 3 times=Probability of getting head*Probability of getting tail*Probability of getting tail

Probability of getting 1 head and 2 tails when flipping a coin 3 times=1/2*1/2*1/2

Probability of getting 1 head and 2 tails when flipping a coin 3 times=1/8

Finally we obtain that the probability of getting the following order: head, tail, tail, is equal to 1/8.
