answer to this will be 1/2. the quesn was that given he has a ladies first policy, what is P(Second letter delivered to a female):If he delivers to ladies first then there will be 2 cases: FM, FF. So the given probability is 1/2

Can you please explain the working? Because it appeared to me a question from conditional probability.

A letter can be delivered to a male or a female employee. However, the postman has a ladies first policy. so what is the probability that the second letter is delivered to a female employee?

If MM is the case then how do you give the second letter to a female? MF can't be a case. A second letter can be given to a female only when the first letter is also given to a female. which means that the cases would only be FM and FF.

I agree with B.. even by Bayes Theorem, the answer is 1/2..

there are 4 possibilities for your two letters: MM, MF, FM and FF. However, since the mailman delivers a female one first no matter what, the only three possibilities are actually MF, FM and FF. Of these, the other letter is from a male in 2 out of the three cases. Thus the answer is 1/3.
