Probability of students given there are groups
A group of 60 second graders is to be randomly assigned to two classes of 30 each.
(The random assignment is ordered by the school district to ensure against any
bias.) Five of the second graders, Marcelle, Sarah, Michelle, Katy, and Camerin,
are close friends. What is the probability that they will all be in the same class?
What is the probability that exactly four of them will be? What is the probability
that Marcelle will be in one class and her friends in the other?
