4.Suppose that in a town,54 percent of the people are male,16 percent of the people are
over 6 feet tall,and 24 percent of the males are over 6 feet tall.
(a) What is the probability that a randomly chosen person from the town is a male and
is over 6 feet tall?
(b) What is the probability that a randomly chosen person from the town is either a male

(c) What is the probability that a randomly chosen person from the town is a male and
is not over 6 feet tall?
A 随即选的人为男性和 B 随即选的人身高在6 feet 以上到底是不是独立事件?
