Each time you buy a pack of cards for a collectible card game, you get 10 random cards out of a pool of 25. The cards in a pack are guaranteed to be distinct, and all cards are equally common. You buy two packs of cards; let X be the number of cards you get twice (once from each pack). What is the name of the distribution of X, and its parameters?
