As аn аvid plаyer оf the Magic the Gathering card game yоu are interested in building a card deck that gives yоu the greatest chance to dominate your opponent.   You have built a deck that you think gives you the best chance of winning by featuring your favorite card, “Uro, Titan of Nature’s Wrath.”  You have put four copies of “Uro, Titan of Nature’s Wrath” in your deck (the most allowed by rule) and 56 other cards to get to the full deck of 60 cards.  Not only is “Uro…” your favorite-looking card, but it is so dominant that you are nearly guaranteed a win if you draw it at least three times during a match.  Sadly, you lost your last match because in the [x] cards you ended up drawing during the match, you only got [y] of your beloved “Uro, Titan of Nature’s Wrath!”  With four Uro cards in your deck, you are reflecting on just how unlucky you are; in fact, now you want to calculate exactly how unlucky you are.  What is the probability that in drawing [x]of your 60 cards you would only draw [y]  “Uro, Titan of Nature’s Wrath?” [Assume that your deck is fully and properly randomized before playing; you have mad shuffling skills so you’re confident this assumption is met.  Also, every time you draw a card it is used and never goes back to the deck]
