Answer:
126 ways
Step-by-step explanation:
Total number of persons = 9
Number of commitees to be chosen = 4
Since, there is no order in the selection process, we use combination.
Choosing a committee of 4 from 9 will be :
9C4.
Recall :
nCr = n! / (n-r)!r!
9C4 = 9! / 5!4!
9C4 = (9*8*7*6) / (4*3*2*1) = 3024 / 24 = 126 ways
