Question

Evaluate C(5, 0)

Answer 1

\( C(n, r) = \dfrac{n!}{(n-r)!~r!}\)

Answer 2

Do you know what factorials are?

For example

10! means

10 * 9 * 8 * 7 * 6 * 5 * 4 * 3 * 2 * 1

Answer 3

But some important things to keep in mind are that

0! = 1
1! = 1

and then the rest are easy to figure out
2! = 2 * 1 = 2
3! = 3 * 2* 1 = 6
