Evaluate the combination:
6C5
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 = 6 and r = 5
| 6C5 2 | 6! |
| 5!(6 - 5)! |
Factorial Formula:
n! = n * (n - 1) * (n - 2) * .... * 2 * 1
Calculate the numerator n!:
n! = 6!
6! = 6 x 5 x 4 x 3 x 2 x 1
6! = 720
Calculate (n - r)!:
(n - r)! = (6 - 5)!
(6 - 5)! = 1!
1! = 1
1! = 1
Calculate r!:
r! = 5!
5! = 5 x 4 x 3 x 2 x 1
5! = 120
Calculate 6C5
| 6C5 = | 720 |
| 120 x 1 |
| 6C5 = | 720 |
| 120 |
6C5 = 6
