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:

请徐小梅老师答疑:对B来说是inversely proportional不一定是m/B的形式吧,也有可能是-mB(m>0)的形式,为什么一定要写成两个变量相乘的形式而不是两个变量相加的形式?

提问:

这个题当时在C和E犹豫了蛮久,而且我看OG答案里也说C might somewhat help to explain。所以这种选项要去判断呢?怎么能准确的定位到正确答案呢? 希望张老师回答一下
