What most of you guys are forgetting is that the randomness in the game is technically pseudo-random and you generally cannot tell pseudo-random from truly random results. You cannot generate true randomness with a computer and pseudo-random results are obtained by plugged some sort of "seed" into a formula. The seed is usually determined by time or some other constantly changing number that the game keeps track of. So concepts such as diminishing probability do not always work all that well with computer generated randomness.
