Evaluate the combination:

16C11

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 = 16 and r = 11

16C11 2	16!
	11!(16 - 11)!

Factorial Formula:

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

Calculate the numerator n!:

n! = 16!

16! = 16 x 15 x 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

16! = 20,922,789,888,000

Calculate (n - r)!:

(n - r)! = (16 - 11)!

(16 - 11)! = 5!

5! = 5 x 4 x 3 x 2 x 1

5! = 120

Calculate r!:

r! = 11!

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

11! = 39,916,800

Calculate 16C11

16C11 =	20,922,789,888,000
	39,916,800 x 120

16C11 =	20,922,789,888,000
	4,790,016,000
