Q.

How many ways are there to select a subcommittee of 7 members from among a committee of 17?

View Answer

Correct choice: B

Explanation:

Since it does not matter what order the committee members are chosen in, the combination formula is used. Committees are always a combination unless the problem states that someone like a president has higher hierarchy over another person. If the committee is ordered, then it is a permutation. C(17,7)= 19,448
125 / 181
