The bookmaker - a trade of the person occupied with reception of monetary rates and payment of winss at game on jumps and races, on results of various sports events, is besides possible reception of rates on outcomes of political and cultural events. The bookmaker man should know thoroughly that kind of sports on which it accepts rates.

By tradition, from time immemorial the hippodrome was a place where sports rates became. So it was moved since Roman empire. After a while to a hippodrome cockfights - entertainment for plebeians have increased. But only only in a XIX-th century the most different kinds of sports have started to become a tote subject. Soon practice has shown, it is possible what to put on everything that runs, jumps, goes and flies. The main thing that the given kind of sports had many admirers. Then the trade of the bookmaker - the professional debater has arisen. There was it in Great Britain which and now keeps the first place in the world both on number of bookmaker offices, and on number of players on a tote.

The trade of the bookmaker is closely crossed with mathematics, combination theory, the theory of probability and statistics. The main task of the bookmaker - not to lose. It should build correctly "line", that is, considering weight of nuances, to define the favourite and the outsider in game and to expose corresponding factors.

As it is known, probability of approach of any in advance unknown event vary in limits from 0 (event is impossible) to 1 (event authentically, that is precisely will come), or if to look in percentage, from 0 % to 100 %. Any event on which reception of rates will be organised is considered by the bookmaker through a prism of probabilities of approach of various "outcomes" of the given event. For example, each fan of sports knows that the football match can end or a victory of one of commands, or a drawn game, and the given outcomes completely settle possible variants of development of a football match (within the limits of rules) as the sum of probabilities of the given outcomes is equal to unit (or 100 %). Thus, for reception of rates the bookmaker should calculate probabilities of a victory of the first command on result of a football match, a drawn game and victories of the second command. For such calculation the statistics of performance of commands who is corrected, proceeding from following additional factors is used: The list injured, motivation of a command and players on a match, a transfer situation, a climate in a command, the club purposes in the tournament which match is analyzed, a place, where a match (in aspect of range of flight, "the" tribunes, house loyalty of arbitrators, etc. will be played.) and others, often not less significant factors.

As a result of such analysis the bookmaker receives values of probabilities of outcomes of event (for the further example we take the following data: with probability 0.5 (50 %) the first command will win, with probability 0.3 (30 %) will be a drawn game and with probability 0.2 (20 %) the second command) will win. If now to divide 1 into each of values (to erect in ?1 degree) we will receive factors which characterise the relation of probability of each outcome to probability of 100 % of approach of the given outcome (as 1 is 100 % probability). In other words, in how many times the probability of approach of each outcome is less than 100 %. In our case 1 / 0.5 = 2; 1 / 0.3 = 3.333; 1 / 0.2 = 5. If to argue abstractly if these two commands will spend infinite number of matches with invariable conditions after summarising it will be found out that every second the first command will win, every fifth - the second, and everyone 3.3333rd will end in a drawn game.

These factors also are the original animators levelling chances of approach of each of outcomes of event at reception of rates. Using these factors, the bookmaker accepts rates as in this case (if probabilities are certainly correctly defined) to it all the same on what of outcomes players will absolutely put. The more probability of approach of a certain outcome, the more its share in aggregate probabilities (100 %), the less than its factor-animator. The bookmaker is ready to pay 5 $ for each $ of the rate on a victory of the second command as on a distance> she will win only every fifth match, that is collecting from the player each match on $, time it will give the collected 5 $ to five matches. But the bookmaker in senses never will offer you 5 $ for each $ of the rate on a victory of the first command as "on a distance" she would win every second match of these commands, that is each two matches the bookmaker would give 5 $, having had time to collect only 2.

From the aforesaid it is possible to draw following unexpected for many a conclusion: the player also does not have any difference on what outcome to stake. An exception are professional players whom, having carried out own factorial analysis (described above) have come to a conclusion that the bookmaker has incorrectly defined probabilities and now overpays for any of outcomes (as it is described on an example of the first command).
