Question

I won tickets to a trip for four to the Super Bowl. I have eight friends but I can only bring three of them. In how many ways can I form my Super Bowl party?

Answer 1

Rip the 4 tickets in half lol

Answer 2

The question is how many ways can we choose 3 from 8. We can use the formula
`(n!)/((n-r)!r!)` where
`n` is 8 and
`r` is 3


`(8!)/((8-5)!5!) = (8!)/(3!5!) = 56` ways of choosing three friends from eight total friends
