What is the probability that a five-card poker hand contains the two of diamonds and the three of spades?(Note: Enter the value in decimal format and report it to four decimal places.)

Answers

Answer 1

Answer: The total probability is 52 choose 5, which is 2598960
Then we multiply the combinations of two diamonds and 3 spades, which is 13 choose 2 times 13 choose 3. That is 22308.
Then we divide to get the decimal. 22308/2598960 is 0.00858343337
