Poker 5 Card

I need an equation that is the probability of getting a whole house in a game of 5 card draw poker.?
Noting that a house 3 is a memory card and 2 of another.
This is usually how they do it. There are a total of C (52.5) hands. To draw a full house, There are 13 possible cards you can draw for the first. And you should call l 'three cards of the same 4 sticks. The second letter can be any of the 12 letters that have not Then you need two created and has 13 * C (4.3) * 12 * C (4,2) probability is [13 * C (4.3) * 12 * C (4,2)] / C (52, 5) other hand, there is another way to think. For the first card, you can choose anything that has the 52/52 cards to choose from. The second is the same card as the first so is 3 / 51 cards that work. The third is 2 / 50 this. The second job is the 48/49 card is not used. The last letter is the same type of card that has 3 / 48 You have to work 1 * 3 / 51 * 2 / 50 * 48/49 * 3 / 48 * C (5,2) ---> there is C (5,2) forms sort of letters. You should not call out in a particular order.
