"The dependent version of the problem would be where we cards are discarded after being drawn. So on the first draw, the deck has 52 cards and 4 aces, and thus there’s a 1/13 chance of drawing an ace. On the second draw there are 51 cards in the deck, so the second draw has a chance of 4/47 of being an ace."<p>Shouldn't that be a 4/51 chance?
