In how many ways can a group of 5 men and 2 women be made out of a total of 7 men and 3 women?
Correct answer: A. 63
- A. 63
- B. 90
- C. 126
- D. 45
Explanation
Choose 5 of the 7 men in 7C5 = 21 ways and 2 of the 3 women in 3C2 = 3 ways. Therefore, the total is 21 x 3 = 63 groups; 90 is a likely error from using an incorrect selection count.

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.
