March 2015 Inthe of each type of 5-card can be computed by calculating the proportion of hands of that type among all possible hands.

Gambling led to the development card hand odds probability theory in the late 1400s.

When playing a game with high stakes, players wanted to know what the chance of winning would be.

In 1494, Fra Luca Paccioli released his work Summa de arithmetica, geometria, proportioni e proportionalita which card hand odds the first written text on probability.

His work from 1550, titled Liber de Ludo Aleae, discussed the concepts of probability and how they directly related to gambling.

However, his work did not receive any recognition because it was not card hand odds until after his death.

His friend, Chevalier de Méré, was an avid gambler with the goal to become wealthy from it.

De Méré tried a new mathematical approach to a gambling game but did not get the desired results.

Determined to know why his strategy was unsuccessful, he consulted with Pascal.

Communicating through letters, the two continued to exchange their ideas and thoughts.

These interactions led to the conception of basic probability theory.

To this day, many gamblers still rely on the basic concepts of probability theory in order to make informed decisions while gambling.

One would then expect to draw this hand about once in every 649,740 draws, that's nearly 0.

For example, the probability of drawing three of a kind is approximately 2.

The cumulative probability is determined by adding one hand's probability with the probabilities of all hands above it.

For instance, with a royal flush, there are 4 ways to draw one, and 2,598,956 ways to draw something else 2,598,960 - 4so the odds against drawing a royal flush are 2,598,956 : 4, or 649,739 : 1.

Hand Distinct hands Frequency Probability Cumulative probability Odds Mathematical expression of absolute frequency 1 4 0.

It can be formed 4 ways one for each suitgiving it a probability of 0.

The 4 missed straight flushes become flushes and the 1,020 missed straights become no pair.

Note that since suits have no relative value in poker, two hands can be considered identical if one hand can be transformed into the other by swapping suits.

So eliminating identical hands that ignore relative suit values, there are only 134,459 distinct hands.

The number of distinct poker hands is even smaller.

However, even though the hands are not identical from that card hand odds, they still form equivalent poker hands because each hand is an A-Q-8-7-3 high card hand.

There are 7,462 distinct poker hands.

The frequencies are calculated in a manner similar to that shown for 5-card hands, except additional complications arise due to the extra two cards in the 7-card poker hand.

It is notable that the probability of a no-pair hand is less than the probability of a one-pair or two-pair hand.

The Ace-high straight flush or royal flush is slightly more frequent 4324 than the lower straight flushes 4140 each because the remaining two cards can have any card hand odds a King-high straight flush, for example, cannot have the Ace of its suit in the hand as that would make it ace-high instead.

Hand Frequency Probability Cumulative Odds 4,324 0.

Since suits have no relative value in poker, two hands can be considered identical if one hand can be transformed into the other by link suits.

Eliminating identical hands that ignore relative suit values leaves 6,009,159 distinct 7-card hands.

The number of distinct 5-card poker hands that are card hand odds from 7 cards is 4,824.

Perhaps surprisingly, this is fewer than the number of 5-card poker hands from 5 cards because some 5-card hands are impossible with 7 cards e.

In most variants of lowball, the ace is counted as the lowest card and straights and flushes don't count against a low hand, so the lowest hand is the five-high hand A-2-3-4-5, also called a wheel.

The frequencies given are exact; the probabilities and odds are approximate.

Hand Distinct hands Frequency Probability Cumulative Odds 5-high 1 1,024 0.

In most variants of lowball, the ace is counted as the card hand odds card and straights and flushes don't count against a low hand, so the lowest hand is the five-high hand A-2-3-4-5, also called a wheel.

The table does not extend to card hand odds five-card hands with at least one pair.

Its "Total" represents 95.

Hand Frequency Probability Cumulative Odds 5-high 781,824 0.

If aces are not low, simply rotate the hand descriptions so that 6-high replaces 5-high for the best hand and ace-high replaces king-high as the worst hand.
