You can think of the problem as follows: You have 13 sets of 4 identical cards, and you first choose two of those sets. Then, to get the two pair, you must choose 2 from the 4 in each set. The remaining card may be chosen from the 11 remaining sets of 4 cards. Thus, the numerator is 13C2 * (4C2)^2 * (11 * 4C1) and the denominator is 52C5.
