One of my students in 8th grade brought me this problem. I am teaching an all level math class but don't recall this equation from back in my day doing math. The problem is this: After a band parent meeting, each of the ten members shook hands with each other once. How many hand shakes were there in all? The formula nCk=n!/k!(n-k)! is supposed to be utilized.
HELP! Please solve entire problem if you can so I can study! :roll:
