There are N players in a tennis tournament. Assuming the initial pairings are done randomly, what are the odds that a certain pair will play each other?

Oops, some mistakes... you say "N must be a power of 2, so N=k^2" -- nope, N=2^K. And then, the number of rounds will be log2(N)=K. See my previous post, "A Special Case".
