The theory of probability (PT) itself is based on the belief that all random events are not random and are subject to a pattern that can be explained mathematically.

THEORY OF PROBABILITY IN BETS Site Wizard
The theory of probability in bets is the study of the influence on them of random events, patterns and operations.

For the first time, scientists became interested in this direction back in the XX century, and for the first calculations they used gambling: roulette and dice. This was done for a reason, but with the aim of explaining the phenomenon of a casino, which always wins in any case. It was then that the first calculations were carried out and formulas appeared that allow calculating the theory of probability for 22 bet app.

To make it clearer, let's look at a specific example. Probably the easiest of these is to flip a coin. As you know, any coin has two sides: heads and tails. If you throw it in the air, it will fall either on one side or on the other, that is, the probability of falling heads and tails will be 50%, 1/2 or 0.5. But in reality this will not happen, and why, we will tell later.

BASIC TERMS

Before talking about what the theory of probability means in sports betting, let's look at the basic terms, which we will need to understand in the future.

Probability is the degree of possibility of a certain event occurring, which is expressed in whole and fractional numbers from 0 to 1.

An event is an outcome that has occurred as a result of performing certain actions. It is of 3 types:

Reliable (the coin will definitely fall);
Impossible (a coin cannot hang in the air);
Random (randomly heads or tails).
The mathematical expectation is the addition of possible outcomes and multiplication by the probability of their obtaining according to 22 bet apk .

Dispersion is the deviation from the mathematical expectation by a certain amount. If, again, consider the example with a coin, you can remember that the probability of getting heads and tails is the same: 50% each. But in fact, one of the sides can fall 5, 10, or even 20 times in a row. This is the deviation from probability. But over a long distance, the situation will level out.
