Problem is: For n greater than or equal to 3, find the number of trees with vertex set {1,2,...,n} with exactly n-2 leaves exactly.

I just applied Cayleys theorem there are n^n-2 trees on that vertex set because there are n^n-2 sequences of length n-2 from the vertex set.

I think this is wrong but cant think of another way to do the problem?
