A committee of 5 people is to be selected from a group of 5 men and 6 women. What is the probability that the committee contains 2 men and 3 women?

Each of 5 cards has one of the letters A, B, C, D and E written on them. The cards are shuffled. What is the probability that the letters A and B are together?
