In how many ways can a committee of 3 be chosen from 8 people?
Answer and explanation
Correct answer: B. 56, from C(8, 3)
- Step 1: Order does not matter, so use combinations. Step 2. C(8, 3) = 8!/(3! 5!) = 56. Answer: 56. Why not the others: 336 counts orderings, and the others are not counting rules for this case.
