Question 707914
There are 12*11*10 = 1320 different ways to choose 3 students from 12 assuming order matters.


If order doesn't matter, then there are 1320/3! = 1320/6 = 220 ways to form the committee.


I'm assuming that each member has an equal role and title. So this would mean that order doesn't matter. If you add titles like president, vice president, etc, then order would matter.
