If people trying to beat the casino studied some sections of probability theory, they would be able to save money.
All games that are available to bizzo casino visitors – roulette, craps, cards, slot machines – are based on the laws of chance. And if in poker or blackjack, the player’s skill and experience can affect the result, then the chances of fans of other entertainments are very little. Only the casino is guaranteed to win.
In roulette, the profit of the institution is guaranteed by the zero section, and in the American version it is also double zero. The wheel, or “turntable”, is divided into 37 cells, 36 of them contain numbers from 1 to 36, and the last one contains zero (there are 38 cells in the USA, of which two are zero). You can bet on specific numbers or groups of numbers or on “equal chances”: black-red and even-odd. The profit from the loss of numbers is much higher than when guessing the color or parity.
If there were no zero cells, the probability of winning for a player who bet, say, on black, would be 18/36, or 50%. But because of one more cell, it is reduced to 18/37. In other words, the institution has an “additional” share of the chance to win – 1/37, that is, 2.7%. In the American version, due to the second zero, the discrepancy is twice as large and amounts to 5.4%.
When a person bets on a specific number, the gambling house also remains in the black, despite the fact that the winnings seem to be generously paid out at the rate of 35 to 1. The chances of a player losing are 36 out of 37, and the chances of winning are only 1 out of 37. That is, for each dollar bet on a specific number, the bizzocasino will receive
the same 2.7%. This does not mean that players are always in the red, but they have much less chances to leave with extra money.
The rules of the game are straightforward: a player (shooter) rolls two dice, and if the sum of points on them is 7 or 11, he wins, if 2, 3 or 12 – he loses. When the dice come up with a different amount, the shooter rolls them to a winning or losing combination. The rest of the participants make bets, trying to guess how the dice will fall.
It would seem that everything is fair, because the casino does not directly participate in the game at all. Nevertheless, the gambling house remains profitable here too. The size of the bets is determined so that the participants receive a win less than the “put”, that is, calculated according to the laws of probability theory. For example, the chances that the combinations 6+6 or 1+1 will fall out on the dice are 1 to 36, but the bet for them is given at the rate of 30 to 1. If the size of the win was proportional to the probability, then the size of the jackpot would be calculated at the rate of 35 k 1. In the same way, the casino underestimates the winnings for other combinations, taking the difference for itself.
Slot machine – A series of failures does not work
The idea is similar to that of the Biarritz strategy: the chance of winning is especially high after a long series of failures. Subconsciously, it seems to a person that it is impossible to lose all the time and after a black streak, he will certainly break the bank.
The creators of the machines are spurring this hope: the “bandits” are programmed to give out winning combinations to a level above or below the main line with an increased frequency. The player sees that the drum is “just a little off”, and again and again throws the tokens into the coin acceptor.
