A group consists of 4 men, 6 women and 5 children. In how many ways can 3 men, 2 women and 3 children selected from the given group?
Correct answer: C. 600
- A. 300
- B. 450
- C. 600
- D. 750
Explanation
Choose the required people independently: ⁴C₃ = 4 ways for men, ⁶C₂ = 15 ways for women, and ⁵C₃ = 10 ways for children. Thus the total is 4 x 15 x 10 = 600 ways. The likely mistake is 450, which results from using an incorrect combination count for one of the groups.

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.
