Evaluate the combination:

12C11

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 = 12 and r = 11

12C11 2	12!
	11!(12 - 11)!

Factorial Formula:

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

Calculate the numerator n!:

n! = 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 (n - r)!:

(n - r)! = (12 - 11)!

(12 - 11)! = 1!

1! = 1

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 12C11

12C11 =	479,001,600
	39,916,800 x 1

12C11 =	479,001,600
	39,916,800

12C11 = 12
