Three different classes contain 25, 38, and 40 students, respectively, and no student is a member of more than one class. If a team is to be composed of one student from each of these classes, in how many different ways can the members of the team be chosen.

Solution

We have 25 choices from first class, 38 from second and 40 from third. The product of 3 choices gives us the team in: 25*38*40 = 38000
