Most important info here... it is SELECTION, so a combinations question that is order does not matter

so choose 2 out of 9 women and 3 out of 7 men = $$9C2*7C3=\frac{9!}{7!2!} * \frac{7!}{4!*3!} = \frac{9*8*7*6*5}{3*2*2}=20*63=1260$$

9C2*7C3 = 1260. Answer is C.

Why is this tagged under probability. This should be tagged under Combinations. Moderators please do the needful. Thanks.

Solution

Given:
• A club consists of 9 women and 7 men
• A committee, of 2 women and 3 men, is to be selected from the club

To find:
• Number of different committees that can be formed

Approach and Working:
From 9 women, we need to select 2 women for the committee.
• Number of ways we can select 2 women = $$^9C_2$$ = 36

From 7 men, we need to select 3 men for the committee
• Number of ways we can select 3 men = $$^7C_3$$ = 35

Therefore, the number of different committees can be formed = 36 * 35 = 1260

Hence, the correct answer is option C.
