提问：
On his drive to work, Leo listens to one of three radio stations, A,
B, or C. He first turns to A. If A is playing a song he likes, he
listens to it; if not, he turns to B. If B is playing a song he likes, he
listens to it; if not, he turns to C. If C is playing a song he likes, he
listens to it; if not, he turns off the radio. For each station, the
probability is 0.30 that at any given moment the station is playing a
song Leo likes. On his drive to work, what is the probability that
Leo will hear a song he likes?
这个题目的0.3为什末代指在A station 播放到了自己喜欢的？不太理解0.3到底指的是甚麽

提问：
PS：总共66个学生，有18个是business major，24个是新生，还有36个什么也不是，我忘了最后是问，仅仅是新生不是business major 的还是仅仅是business major不是新生的？
构筑答案：好像答案不是12 就是16.。。
解析：
18和24代表的韦恩图圈圈有重合，36代表的是自己单独的圈圈。
Total =66； 36个学生不在Business和Fresh 范畴里面，所以F+B=30;
F 和B的共有学生=12，
是B不是F=6； 是F不是B=12。
