this looks like a riddle o-o

mhanifa:

This is about combinations. Do you have an idea?

mhanifa:

Ok. It says no restrictions but one person can't be in the committee. So you need a combination of 5 out of 6 + 4 - 1 = 9 people. Do you know how to find this?

mhanifa:

This is going to be: 9C5 = 9!/5!(9-5)! Can you calculate this?

mhanifa:

9C5 = 9!/5!(9-5)! = 6*7*8*9/2*3*4 = 126

mhanifa:

Hope this helps
