Assume that each postal delivery is independent of every other postal delivery, and assume that if a wife receives a letter from her husband, she will certainly mail a response to her husband. Suppose a man in country X mails a letter to his wife （also in country X） through the postal system. If the man does not receive a response letter from his wife, what is the probability that his wife received his letter?
A.1/3
B.3/5
C.2/3
D.2/5
Solution: D
（Notices: if the wife did not receive the letter, she would not send response to the man.）Note:
A: the wife received the letter;
: the wife did not received the letter;
B: the man received a response letter from his wife;
: the man did not receive a response letter from his wifeThe question “If the man does not receive a response letter from his wife, what is the probability that his wife received his letter?” is equal to figure out P（A|）。
