Question

Math help

Answer 1

This question is an example of a "combinations" question, where you want to make a selection but the order does not matter. On this one we're trying to do 10 choose 5, meaning that the formula you want to set up is

C(10,5) = 10! / 5!(10 - 5)! = 252

So there are 252 different ways that you could pick any 5 members out of a group of 10

Answer 2

There are 2 fives in group of 10. so each member should have 5 chances or less to be picked up
