How many ways can you line the nine members up for an interview?

Answer 1

Answer 6)

Here we have n = 5 men + 4 women = 9

R = 3 (vice, chair and secretary)

As here order is important we will use permutations

Npr = n!/(n-r)!

9!/(9-3)! = 504

7)

We can line up n members in n! Ways

So, answer here is 9! = 362880
