A Simple Probability Problem I Just Can't Get

A simple problem that has me stumped:

Suppose you toss three dimes into the air and they land on the floor. What is the probability that two dimes will land heads up and one will land tails up?

I need help setting up a probability tree/chart.

Thanks!

There are only eight possible outcomes:
HHH
HHT
HTH
HTT
THH
THT
TTH
TTT.

Count the favorable outcomes.
