I have no idea how to do this question can some one help me please!?

In how many different ways can the following positions be chosen from the 18-member math team?
president¸ vice-president¸ and treasurer

Respuesta :

The answer should be 108. Because you have 6 different possible ways for each person. So you multiply 18 by 6. Which is 108. I am pretty sure that is how you solve this problem.
