Hi All,

The answer choices to this question provide an interesting 'shortcut' that you can use to avoid some of the math involved.

We're told that Amanda is going to buy 3 different board games (from a total of 6 different possible games). Since the order of the games does NOT matter, we're dealing with a Combination Formula calculation:

Combinations = N!/K!(N-K)! where N is the total number of items and K is the size of the subgroup.

N = 6 and K = 3

6!/3!(6-3)! = (6)(5)(4)(3)(2)(1)/(3)(2)(1)(3)(2)(1) = (6)(5)(4)/(3)(2)(1) = 20 different combinations of 3 games.

Since we already have 20 different options, including a ball will only INCREASE the number of possibilities. There's only one answer that fits...

Final Answer:

GMAT assassins aren't born, they're made,
