"Give me a coin. <Takes Coin.> All right. Uh... heads, I win, tails, you lose. Right? <Flips coin.> Tails, you lose." -Ralph Kramden All things being equal, you're well aware that if you flipped a completely fair coin, you'd have a 50% chance of it landing on heads, and a 50% chance of landing on tails (ignoring the side, of course).
