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:

老师好 我这道题的方法就是解二次方程,只有唯一正解才能证明是充分的。(我发现很多应用题都是这样)但是我发现解二次方程很浪费时间,考试的时候可能没那么充分的时间,怎么办呢?这道题还有更好的方法吗?谢谢老师
