7. Textbook 2.44: A fleet of nine taxis is to be dispatched to three airports in such a way that three go to airport A, five go to airport B, and one goes to airport C. Assume that taxis are allocated to airports at random. (a) If exactly one of the taxis is in need of repair, what is the probability that it is dispatched to airport C? (b) If exactly three of the taxis are in need of repair, what is the probability that every airport receives one of the taxis requiring repairs?
