There are two positions in the company and five applicants for the same, two women and 3 men. The probability p(x) has to be determined where x is the number of women chosen to fill the positions.

The total number of ways in which the positions can be filled is given by C(5, 2).

When x number of women fill the positions we have x number of women filling the positions in C(2, x) ways and 2-x women not filling the positions in C(3, 2-x) ways. This gives the number of ways in which x women can fill the positions as the product C(2, x)*C(3, 2-x)

The probability that the positions are filled by x women is  C(2, x)*C(3, 2-x)/C(5, 2)

The value of x can be 0, 1 or 2.

The required value of p(x) = C(2, x)*C(3, 2-x)/C(5, 2)
