Zhengdan同学你好,这个题目确实绕口,知识点是不难的,将英文转化为数学语言为解题的关键
Suppose that 5 percent of the stocks (meeting your stock-selection criteria) are in the telecommunications (telecom) industry.
假设 (满足你股票选择标准)的5%股票是通信行业的。这个事件为P(A)
Also, dividend-paying telecom stocks are 1 percent of the total number of stocks (meeting your selection criteria).
那些支付股利的通信行业股票 占了 (满足你股票选择标准)总股票的1%。 这个事件为P(AB)
What is the probability that a stock is dividend paying, given that it is a telecom stock that has met your stock selection criteria?
已知一个通信行业股票满足你的股票选择标准,那么这只股票是支付股利的股票概率是多少?这个事件为P(B│A)
利用P(AB)=P(A)*P(B│A)求解
