What is the probability that a deck of poker draws 5 cards in pairs?

After careful calculation, the probability of discovery is so high. There are 54 cards in a deck, and 5 cards * * *: (54 * 53 * 52 * 51* 50)/(5 * 4 * 3 * 2 *1) = 62010. The other is whether there is a king: (13 *12 *1*10 * 9)/(5 * 4 * 3 * 2 *1) * 4 = 5. 2= 1430 does not have a pair1* * has: 5 148+ 1430=6578 has a pair: 620 10-6578=55432. The probability is actually: 55432.
