Hi All,
This question can be solved with the Combination Formula:
N!/[K!(N-K)!] where N is the total number of items and K is the number in the sub-group.
We're told that we have to form a committee of 5 members from a total pool of 8 members, so N=8 and K=5. Using the Combination Formula, we have...
8!/[(5!(8-5)!] =
(8)(7)(6)(5)(4)(3)(2)(1) / (5)(4)(3)(2)(1)(3)(2)(1) =
(8)(7)(6) / (3)(2)(1) =
(8)(7) / 1 =
56 different combinations of 5 members.
Final Answer:
GMAT assassins aren't born, they're made,
Rich
