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
or is over 6 feet tall?
(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?
我觉得是但是又找不到证据,老师和我们说的独立事件的条件就是P（A交B）=P（A）P（B）但是这里的a小题我就发现不是这么回事的,需要用 P（A）P（B l A）才能算出来.但是我又觉得这两个事件是独立事件,求助到底是不是如果不是的话求解b

不是独立事件 P（A+B）=P(A)+P(B)-P(AB) 其中P(AB)就是a小题的答案然后把P(A)=0.54和P(B)=0.16代入就可以了
