Evaluate the combination:
14C4
A unique order or arrangement
nCr = | n! |
r!(n - r)! |
where n is the number of items
r is the unique arrangements.
14C4 2 | 14! |
4!(14 - 4)! |
n! = n * (n - 1) * (n - 2) * .... * 2 * 1
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
(n - r)! = (14 - 4)!
(14 - 4)! = 10!
10! = 10 x 9 x 8 x 7 x 6 x 5 x 4 x 3 x 2 x 1
10! = 3,628,800
r! = 4!
4! = 4 x 3 x 2 x 1
4! = 24
14C4 = | 87,178,291,200 |
24 x 3,628,800 |
14C4 = | 87,178,291,200 |
87,091,200 |
14C4 = 1,001
14C4 = 1,001
