exactly i don't know? that is the question?

it has somthing to do with factorials

Answer 1

(n)
(r)
You evaluate this by the following formula
n!/(r !)(n-r)! or use the nCr key on calculator

Ex:
(5)
(2)
= 5!/(2! * 3!) getting the 3 from 5-2
=5*4*3*2*1/(2*1*3*2*1) which after cancelling, leaves you
= 10

Answer 2

Sorry, but what do you mean by numerical form?
Please explain!
