A subset A of the set `X = {1.2,3.....100}` is chosen at random. The set X is reconstructed by replacing the elements of A, and another subset B of X is chosen at random. Then the probability that `A nn B` contains exactly 10 elements is

A subset A of the set X={1,2,3,..,100} is chosen at random. The set X is reconstructed by replacing the elements of A, and another subset B of X is chosen at random. The probability that A cap B contains exactly 10 elements, is
