Step-by-step explanation:
formula is
nCr = n!/(r!(n−r)!)
r= 8 = number of choosing objects from the set
n = 11 = total number of objects in the set
C(n,r)=C(11,8)
=11!/(8!(11−8)!)
! means factorial
factorial means to multiply by decreasing positive numbers.
For example, 8! = 8 ∗ 7 ∗ 6 ∗ 5 ∗ 4 ∗ 3 ∗ 2 ∗ 1 = 40320
=11!/8!×3!
= 165
