Question 765774: In a class of 9, there are 3 students who forgot their lunch. If the teacher chooses 2 students, what is the probability that neither of them forgot their lunch? Answer by rothauserc(4718) (Show Source):
You can put this solution on YOUR website! the probability that the first student picked has a lunch is 6/9 or 2/3
the probability that the second student picked has a lunch is 5/8
========================================================================
the probability that both students have a lunch is 2/3 * 5/8 = 10/24 = 5/12
