14 Combinations of 12 MathCelebrity logo Image to Crop

Evaluate the combination:

14C12

Combination Definition:

A unique order or arrangement

Combination Formula:
nCr  =  n!
  r!(n - r)!

where n is the number of items
r is the unique arrangements.

Plug in n = 14 and r = 12
14C12  2  14!
  12!(14 - 12)!

Factorial Formula:

n! = n * (n - 1) * (n - 2) * .... * 2 * 1

Calculate the numerator n!:

n! = 14!

14! = 14 x 13 x 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

14! = 87,178,291,200

Calculate (n - r)!:

(n - r)! = (14 - 12)!

(14 - 12)! = 2!

2! = 2 x 1

2! = 2

Calculate r!:

r! = 12!

12! = 12 x 11 x 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1

12! = 479,001,600

Calculate 14C12
14C12  =  87,178,291,200
  479,001,600 x 2

14C12  =  87,178,291,200
  958,003,200
