How many complete bipartite graphs have n vertices?

2. Relevant equations

3. The attempt at a solution

I said, let the first bipartition set have x vertices and the second bipartition set have y vertices. So x+y=n.

I think that you would do C(n, x)*C(n-x, y)=C(n,x)*C(y,y)=C(n,x) but I feel like this is either wrong or not good since I made x and y up arbitrarily.

Help?
