This means that for every 36 spins when the number does not fall, there will be one case when the selected number falls. In this case, the odds will be written as 36 to 1. Here, too, we will remain at the probability for the single number at roulette. Using the example above 1/37, this means that the single number on the roulette will hit one time out of 37 spins.Įxpression by the odds (x to 1) - Each time X occurs, the chosen phenomenon happens one time. In numerical terms, we use the calculation of percentages. probability that the single number on the roulette (Straight) will fall: 1/37 * 100 = 2.7%Įxpression using fractions (1 / x) - If we express the probability using a fraction, we say that the phenomenon occurs 1 time from X attempts. We can also use fractions or ratios.Įxpression as a percentage (%) - Probability is calculated as (Event / Outcomes) * 100. There are several ways to write down a probability. Note: All numbers in the article refer to European Roulette - so we count on 37 numbers. Everything in a casino is related to the probability and house edge. And thanks to it, the casino always wins over the long run. Anyone who runs a casino or makes online casino games knows the probability theory very well.
