Probability and gaming have been an idea since long before the invention of poker. The evolution of probability theory in the late 1400s was attributed to gambling; when playing a game with high stakes, players wanted to know what the chance of winning would be. In 1494, Fra Luca Paccioli introduced his work Summa de arithmetica, geometria, proportioni e proportionalita which was the initial written text on probability. Motivated by Paccioli’s job, Girolamo Cardano (1501-1576) made additional improvements in probability theory. His job from 1550, titled Liber de Ludo Aleae, discussed the concepts of chance and the way they had been directly associated with gambling. However, his work didn’t get any recognition since it wasn’t published until after his death. Blaise Pascal (1623-1662) also contributed to probability theory. His friend, Chevalier de M??r??, was an avid gambler using the wish to become wealthy from it. De M??r?? tried a new mathematical approach to a gambling game but didn’t get the desired benefits. Determined to know why his strategy was unsuccessful, he consulted with Pascal. Pascal’s work with this problem began an important correspondence between him and fellow mathematician Pierre de Fermat (1601-1665). Communication through letters, both continued to exchange their ideas and thoughts. These interactions resulted in basic probability theory’s conception. To this day, many gamblers still rely on the basic concepts of probability theory so as to make informed decisions while betting.
The next graph enumerates that the (absolute) frequency of each hand, given all combinations of 5 cards randomly drawn from a full deck of 52 without replacement. Wild cards are not considered. In this chart:
Different hands is the number of distinct techniques to draw on the hands, not counting different matches.
Frequency is the number of methods to draw on the hand, including the card worth in suits.
