You can put this solution on YOUR website! Abe, brian, and Carmela share the responsibility of caring for the family pets. during a seven day week, abe and brian each take 3 days and carmela takes the other one. in how many different orders can the days of a week be assigned?
-----------------
Assign three to abe: 7C3 = 35 ways
Assign three to brian: 4C3 = 4 ways
Assign one to carmela: 1C1 = 1 way
-----------------------
Total number of ways: 35*4*1 = 140
