In an auto body shop, it is known that the average number of paint blemishes per car is 3. If 2 cars are randomly chosen for inspection, what is the probability that:
(a) the first car has no more than 2 blemishes?
(b) each of the cars has no more than 2 blemishes?
(c) the total number of blemishes in both of the cars combined is no more than 2?
