A poker hand consists of five cards drawn from a deck of 52 cards. Each card has one of 13 denominations (2, 3, 4, ..., 10, Jack, Queen, King, Ace) and one of four suits (Spades, Hearts, Diamonds, Clubs). Determine the probability of drawing a poker hand consisting of two pairs (two cards of one denomination, two cards of a different denomination, and one card of a denomination other than those two denominations). The probability of drawing a poker hand consisting of two pairs is. (Type an integer or decimal rounded to four decimal places as needed.)
