Difficulty: Easy
Correct Answer: 210
Explanation:
Introduction / Context:
With no restrictions, the number of committees depends only on total group size and committee size. Gender labels do not matter for counting unless constraints are imposed.
Given Data / Assumptions:
Total people = 10; committee size = 4.
Concept / Approach:
Use combinations C(10, 4) since order of selection does not matter.
Step-by-Step Solution:
Verification / Alternative check:
Symmetry: C(10, 4) = C(10, 6) = 210.
Why Other Options Are Wrong:
225, 195, 185 do not equal C(10, 4).
Common Pitfalls:
Using permutations instead of combinations.
Final Answer:
210
