The probability of a man’s selection p = 1/4
The probability of a man’s not selection q = 1- 1/4 = 3/4
The probability of a woman’s selection P = 1/3
The probability of a woman’s not selection Q = 1 - 1/3 = 2/3
probability of none selection of both of them = P*Q = 3/4 * 2/3 = 1/2
the probability that both of them will be selected = 1 - probability of none of them will be selected = 1 - 1/2
= 1/2 Ans
