A coin will be flipped three times. The result of each flip is either heads (h) or tails (t). The outcome hth represents the first result is heads, the second result is tails, and the third result is heads. The list of all possible outcomes is shown. If the result of the first flip is tails, what is the probability that the coin lands on heads two times?
