Activity 4

We are going to elect a "student council" from the members of our class (24 total students).

1. In how many ways can we pick a President, Vice President, and Secretary?
• 24! / (24-3)! = 24! / 21! = 24*23*22

 

2. In how many ways can we do this PLUS pick a Treasurer and “Sergeant at Arms”
• 24! / (24-5)! = 24! / 19! = 24*23*22*21*20
