For example, when playing European Roulette with a wheel with 37 slots (numbers 0 to 36), the probability of a particular number appearing is 1/37, or about 2.7%. This means that in the long run, you can expect your winnings to be in line with this probability, but in the short run, you will see huge fluctuations. Therefore, it is important to play patiently and have a long-term plan.
