Difficulty: Easy
Correct Answer: 24
Explanation:
Introduction / Context:
We select fixed counts from each subgroup. Order of members on a committee is irrelevant, so use combinations.
Given Data / Assumptions:
Concept / Approach:
Compute C(4,3) * C(4,2) by independence across disjoint groups.
Step-by-Step Solution:
C(4,3) = 4.C(4,2) = 6.Total = 4 * 6 = 24.
Verification / Alternative check:
Enumerating men first, then women, or vice versa, yields the same product.
Why Other Options Are Wrong:
20 and 16 are near-miss counts (e.g., forgetting some combinations); 15 is C(6,2) and unrelated.
Common Pitfalls:
Accidentally using permutations or mixing order into a committee selection.
Final Answer:
24
