32 Combinations of 4

---

Evaluate the combination:

₃₂C₄

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 = 32 and r = 4

32C4  2	32!
	4!(32 - 4)!

Factorial Formula:

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

Calculate the numerator n!:

n! = 32!

32! = 32 x 31 x 30 x 29 x 28 x 27 x 26 x 25 x 24 x 23 x 22 x 21 x 20 x 19 x 18 x 17 x 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

32! = 263,130,836,933,693,517,766,352,317,727,113,216

Calculate (n - r)!:

(n - r)! = (32 - 4)!

(32 - 4)! = 28!

28! = 28 x 27 x 26 x 25 x 24 x 23 x 22 x 21 x 20 x 19 x 18 x 17 x 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

28! = 304,888,344,611,713,836,734,530,715,648

Calculate r!:

r! = 4!

4! = 4 x 3 x 2 x 1

4! = 24

Calculate ₃₂C₄

32C4  =	263,130,836,933,693,517,766,352,317,727,113,216
	24 x 304,888,344,611,713,836,734,530,715,648

32C4  =	263,130,836,933,693,517,766,352,317,727,113,216
	7,317,320,270,681,131,518,678,783,754,240
