The joint probability of events A and B is 32 percent with the probability of event A being 60 perce
The joint probability of events A and B is 32 percent with the probability of event A being 60 percent and the probability of event B being 50 percent.Based on this information,the conditional probability of event A given event B has occurred is closest to:
The joint probability of events A and B is 32 percent with the probability of event A being 60 percent and the probability of event B being 50 percent.Based on this information,the conditional probability of event A given event B has occurred is closest to:
这题的意思应该是事件A和事件B同时发生的概率是32%,事件A单独发生的概率是60%.这是GMAT里面的题目吗?楼主说详细点啊
再问： 不好意思题目没copy完整
再答： 我觉得这道题目的意思是：事件A和事件B同时发生的概率是32%，事件A单独发生的概率是60%，事件B 单独发生的概率是50%。现在求在B发生的前提下A发生的概率。 我数学不是很好，但是我查了一下，这类题属于条件概率 。条件概率的公式是P（A|B)=P(AB)/P(B) P(AB)=P(A)*P(B) 所以答案可能是16/25 但具体怎么做我也不是很清楚 对不起哈 我可以再帮你问问同学
