Question

I need help with this problem: A 12-member committee is going to choose a chairman, vice-chairman, and secretary. In how many ways can these people be chosen? A. 36 ways B. 1320 ways C. 1728 ways D. 79,833,600 ways

Answer 1

so 12 members
they have 3 slots
assuming they choose from the group of 12 members
12 choices for the first slot
2nd slot: 1 is taken so 12-1=11 choices for the second
3rd slot: 2 are taken so 12-2=10 choices for te 3rd

answer is 12 times 11 times 10=1320=B

the answer is B
