The answer is A.
Total number of possible teams = 7C4 = 7!/(4!*3!) = 7*6*5/3! = 7*5 = 35
Teams with Denise, Evan, and Alice together = Choose DEA + 4C1 = 4C1 = 4
--> Teams where D, E and A do not all play together = 35 - 4 = 31
Total number of possible teams = 7C4 = 7!/(4!*3!) = 7*6*5/3! = 7*5 = 35
Teams with Denise, Evan, and Alice together = Choose DEA + 4C1 = 4C1 = 4
--> Teams where D, E and A do not all play together = 35 - 4 = 31
