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

老师,这道题为什么要用现在完成时呢?我觉得用蛇起源于四腿蜥蜴不是持续的动作,也没有持续的影响

请问老师这道题做题思路,可以理解为消序处理吗?比如八个字母排一列,A,B,C三个字母顺序不影响,排列方式为A(8,8)除A(3,3),如果是,为什么这么用?
