Out of 6 men and 4 women, a committee of 5 members is to be formed so that it has 2 women and 3 men. In how many different ways can it be done:

Solution

✅ Correct Option: 4

The committee needs 5 members with exactly 2 women and 3 men from a group of 6 men and 4 women.

Since the order of selection doesn't matter for a committee, combinations are used.


The number of ways to choose 2 women from 4 women:

C(4,2)=4!2!×2!C(4,2) = \dfrac{4!}{2! \times 2!}

C(4,2)=4×32×1C(4,2) = \dfrac{4 \times 3}{2 \times 1}

C(4,2)=122C(4,2) = \dfrac{12}{2}

C(4,2)=6C(4,2) = 6


The number of ways to choose 3 men from 6 men:

C(6,3)=6!3!×3!C(6,3) = \dfrac{6!}{3! \times 3!}

C(6,3)=6×5×43×2×1C(6,3) = \dfrac{6 \times 5 \times 4}{3 \times 2 \times 1}

C(6,3)=1206C(6,3) = \dfrac{120}{6}

C(6,3)=20C(6,3) = 20


The total number of ways to form the committee:

Total ways =C(4,2)×C(6,3)= C(4,2) \times C(6,3)

Total ways =6×20= 6 \times 20

Total ways =120= 120

Therefore, the committee can be formed in 120 different ways.
