In how many different ways can four people be put into three subsets containing two people, one person, and one person?

Call the people  A, B, C, D

 

Possible sets

 

(A B) (C) (D)

(A C)  (B) (D)

(A D) (B) (C)

(B C) (A)(D)

(B D) (A) (C)

(C D) (A) (B)

 

Another way to see this....just  pick any  2 of 4 people for the first set =  C (4,2)  =  6 sets
