Suppose there is a group of seven people from which we will make a committee.
In how many ways can we pick a five-person committee?
Answer by algebrahouse.com(1659) (Show Source): You can put this solution on YOUR website!
This is a combinations problem, where you are choosing 7....5 at a time.

Grab a scientific calculator and locate the permutations and combinations button.
It might be labeled nPr and nCr.
You want to use nCr for combinations.

You are choosing 7....5 at a time.
So, type in 7c5

You should get 21.
