Question 895493: Prove that C(n,0) = 1

You can put this solution on YOUR website!
0! is defined as 1.

C(n,0) = n%21%2F%280%21%2A%28n-0%29%21%29 = n%21%2F%281%2An%21%29 = cross%28n%21%29%2F%281%2Across%28n%21%29%29 = 1

But the real proof is by common sense:

If you have n things, then the number of ways you can choose
to take 0 of them is 1 way, -- and that 1 way is to not take any!
