In a life full of fluctuations, just a small change can make an event happen in a completely different direction and like the Domino effect, it leads to a series of other changes.

This is described in the famous butterfly effect by meteorologist and chaos theory expert Edward Norton Lorenz in 1972, but in many cases we can fully list the events. can happen.

Then we have a sample space where we can calculate the likelihood of that event happening, which mathematicians call it probability. This is a concept first introduced by mathematician Girolamo Cardano in 1526.

It then became the premise for a new branch of mathematics: probability theory. In fact, gambling or black jack also follows the rules of probability. Capital probability is an objective matter, so winning or losing in gambling is also purposeful, unlucky, random.

Although there are many forms of gambling (soccer betting, online betting, number cards, Blackjack, crab ball, forward hand, mahjong, paddle etc) and each has its own rules, The rules of the game, the odds of winning are different, but the dealer always has an advantage over the player.

First, the house always has enough knowledge, skills or even tricks, tricks, deep experience in the game that they own, while the player (mostly “fuzzy chicken”) is difficult to compare. comparable in this clause.

The bookie always has a strong financial resource, a professionally diversified human and talent resource in order to collect information, so there is a deeper and more scientific analysis than the player.

They have advantages that players do not have such as:

Game rules: is a method of play that the dealer offers in which the dealer sets a rule in his favor (for example, in blackjack if both the player and the dealer win, the player will still lose because of the petition. That is simply the law that the house makes).

Moreover, this advantage also means that the house also affects on the total bet (plus the winnings), not just the amount you bring, when you play on the winning amount also means that the dealer will have. advantage increases.

Second, in general, even if you win, it does not mean that the dealer has lost, the profit that the house gets is in all the players, not the individual, the customer. , the bigger the player, the higher the commission rate the dealer has.

In the roller tables in the province of Manitoba (Canada), the roller wheel has 37 numbers (1 to 36 and 0). The theoretical probability that the player thinks they will win will be 1/37, however the actual probability of the dealer will be 1/35 (slightly better than the player 2.7%).

- In American Roulette (consisting of 38 numbers), the player’s odds of winning are 1:37 and the payout in case of the player winning is 1:35. And the house has the advantage of 1/19 (about 5.26%).

In Baccarat, the house edge is 1.25%. - In Blackjack, because the rules are different at different locations, the house advantage is only 1%.
- In the lottery game, if you hit 2 numbers on the tail, it will only eat 70 times, this probability is very small (1/100) while the dealer has a 30% chance of winning.
- Examples of other common gambling genres where the house has a probability advantage: Pai Gow, Let It Ride, blackjack, 3-card poker and Caribbean poker, mini- baccarat, poker (poker) …
