At a certain meeting of 25 people, they decide to select a committee, which would have a chairman and 2 members. How many ways are there to do it?
There are 25 ways to choose the chairman followed by $24C2$ to choose the two remaining members. So the answer would be $25 * 24C2$ = 6900.
I just wanna double check this is the right way to do it. Thanks!
