A hair salon has three stylists. One of them is excellent, one is average, and, unfortunately, one is very poor. Every morning, the three stylists style each other's hair -- of course, no one styles her own hair, each one works on the hair of one of the other two ladies, and who styles whom is selected at random.
One day you walk into the shop to get your hair styled. Which stylist should you select in order to look your very best?
Suppose you are satisfied enough to return to the shop a second time. Whom should you select now?
(Please be sure to explain your answer.)
