Suppose someone told you they had a nice conversation with someone on the
train. Not knowing anything else about this conversation, the probability
that they were speaking to a woman is 50%. Now suppose they also told you
that this person had long hair. It is now more likely they were speaking to
a woman, since most long-haired people are women.

然后计算confidence interval
不是很难的样子
