This one seems simple, but I want to be sure I'm using the correct thinking. 1. The problem statement, all variables and given/known data If there are 30 students in a class and 5 of them are to be assigned A's, 20 to be assigned B's, and the remainder C's, how many different sets of students receiving A's are possible? 2nd Part Determine the probability of a group of 5 students being selected at random and none of the 5 being assigned an A. 2. Relevant equations None 3. The attempt at a solution Would this be just a 30 choose 5 question since there are 5 students who can make an A out of 30?
