Question 1140302: How many ways are there to divide 6 students into a group of 3 students, a group of
2 students, and a group of 1 student, so that no student is in more than one group? Answer by ikleyn(52805) (Show Source):
You can choose, first, the set of 3 students among 6 of them in = = 20 ways.
You then can choose the set of 2 students among the remaining 3 = 6-3 students in = 3 ways.
And after that, you just have no any choice for the remained 1 = 6 - 3 - 2 student.
In all, you have 20*3 = 60 ways to do what is assigned. ANSWER
