A committee has 5 men and 6 women. What are the number of ways of selecting a group of eight persons?
Correct answer: A. 165
- A. 165
- B. 185
- C. 205
- D. 225
Explanation
There are 5 + 6 = 11 committee members, and selecting 8 without regard to order gives 11C8 = 11C3 = (11 x 10 x 9)/(3 x 2 x 1) = 165 ways. The likely trap is option b, 185, from using an incorrect combination value or treating the selection as ordered.

About Sequences and Series
Sequences describe ordered terms formed by a pattern, while series represent the sum of those terms. Questions cover arithmetic and geometric sequences, their nth terms, common difference or ratio, finite sums, and applications, with the sequence itself kept distinct from the corresponding series.
