Let nCk denote all the combinations of n objects in groups of k elements. It should be obvious that we need to work with combinations and not permutations as the order of the cards in our hand of cards is irrelevant.
I have been working on the problem of probability of poker hands, I have been able to calculate the probability of each hand except one pair and high card hand. Here is what I have. P1 P2 X1 X2 X3(here P1 P2 are the same) 13C1. 4C2 (total counts of one pair) Now total counts of 3 cards distinct from the pair cards.
- Probability And Statistics: Hi. My name is Paul. I have a Masters Degree in Applied Mathematics and a Bachelors Degree in Mathematics, both from the University of Maryland. I enjoy doing probability problems much like some enjoy doing crossword puzzles. Currently, I am reviewing through a college senior-level probability and s.

- Probability in Poker. Caleb is playing a poker game with his buddies, and he's having a lot of luck. After winning a hand with a flush, Caleb begins bidding high again on the next hand.
(a) We have to select one suit out of 4 which can be done in 4C1 ways and, once the suit is chosen, we have to select 5 cards from that specific suit and this can be done in 13C5 ways. Finally, in a game of poker there are 52C5 possible hands. Hence, the probability of a flush is given by
(4C1 x 13C5)/ 52C5 = 0.001981 or 0.1981%

For part (b) we follow the same approach, but this is more complicated. In fact, in this case, we must recognize that
i) A pair can be formed in 13C1 ways. Once the card that forms the pair has been selected, we must choose 2 of the 4 cards with that particular number of them, i.e. 4C2.
ii) Then we have to choose other 3 cards from the other denominations, i.e. 12C3 and then for each of these cards we have 4C1 ways to select a card with that number of it.
Hence the probability of one pair is
(13C1 x 4C2 x 12C3 x 4C1 x 4C1 x 4C1)/ 52C5 = 0.4226 or 42.26%
For (c ) we have 13C2 ways to select what denominations will be used to form the 2 pairs, and once the two denominations are chosen, for each, we have 4C2 ways to select the two cards. The remaining card can be chosen from the remaining 11 denominations, i.e. 11C1 and then we have 4C1 ways to select the card from any of those denominations.
Thus the probability of exactly two pairs is
(13C2 x 4C2 x 4C2 x 11C1 x 4C1) / 52C5 = 0.0475 or 4.75% Is there legal gambling in nashville tennessee.
We should now be sufficiently familiar with the arguments to use for part (d) and I will not provide all the details, but just the answer, i.e.:
(13C1 x 4C3 x 12C2 x 4C1 x 4C1) / 52C5 = 0.0213 or 2.13%
To find the probability of four of a kind, we have to select one denomination to use and then complete it with another card chosen among those the remaining 48 cards, i.e.
