From a total of 5 boys and 4 girls, how many 4-person committees can be selected if the committee must have exactly 2 boys and 2 girls?
A. 16
B. 24
C. 60
D. 120
E. 240
The OA is C.
I solved this PS question as follows,
2 boys can be selected from 5 boys in 5C2 ways = 10 ways
2 girls can be selected from 4 girls in 4C2 ways = 6 ways
Hence total number of ways = 10 * 6 = 60 ways.
Hence option C.
Can anyone explain another way to solve this question, please? Thanks!
