From 7 men and 5 women, choose committee of 4 with at least 1 woman:
AJust C(12,4)
B35
CC(12,4) - C(7,4) = 495 - 35 = 460
D100
Answer & Solution
Correct answer: C. C(12,4) - C(7,4) = 495 - 35 = 460
Complementary: all-men committees = C(7,4) = 35. Total committees = C(12,4) = 495. With at least 1 woman = 495 - 35 = 460.
