A coin is flipped five times. For each of the events described below, express the event as a set in roster notation. Each outcome is written as a string of length 5 from (H, T}, such as HHHTH. Assuming the coin is a fair coin, give the proba- bility of each event. (a) The first and last flips come up heads. (b) There are at least two consecutive flips that come up heads.
