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 are drawn. * * Yes: (54 * 53 * 52 * 51* 50)/(5 * 4 * 3 * 2 *1) = 62010. There are two situations where there are no pairs. One is that there is no king. The other is whether there is a king: (13 *12 *1*10 * 9)/(5 * 4 * 3 * 2 *1) * 4 = 5. 2= 1430 pairs 1 * * is: 5 148+ 1430=6578 pairs are: 620 10-6578=55432. The probability is actually: 55432/620 12.
