Suppose that the probabilities are, respectively, 0.40,0.40, and 0.20 that in city driving a certain kind of imported car will average less than 22 miles per gallon, anywhere from 22 to 25 miles per gallon, or more than 25 miles per gallon. Find the probability that among 12 such cars tested, 4 will average less than 22 miles per gallon, 6 will average anywhere from 22 to 25 miles per gallon, and 2 will average more than 25 miles per gallon.
