Evaluate the combination:
3C0
Combination Definition:
A unique order or arrangement
Combination Formula:
| nCr = | n! |
| r!(n - r)! |
where n is the number of itemsr is the unique arrangements.
Plug in n = 3 and r = 0
| 3C0 2 | 3! |
| 0!(3 - 0)! |
Factorial Formula:
n! = n * (n - 1) * (n - 2) * .... * 2 * 1
Calculate the numerator n!:
n! = 3!
3! = 3 x 2 x 1
3! = 6
Calculate (n - r)!:
(n - r)! = (3 - 0)!
(3 - 0)! = 3!
3! = 3 x 2 x 1
3! = 6
Calculate r!:
r! = 0!
0! =
0! = 1
Calculate 3C0
| 3C0 = | 6 |
| 1 x 6 |
| 3C0 = | 6 |
| 6 |
3C0 = 1
