This one's not hard if you spot the answer, but I think it deserves a little explanation (sorry royalchicken, no elaborate proofs required):

Vaknso and Rhymester are playing a game. Vaknso tosses a coin 10 times, Rhymester only 9; both record the number of heads they got. If Vaknso gets more heads than Rhymester, he wins; otherwise Rhymester wins. Assuming neither cheats, what is the probability that Rhymester wins?
