Roulette is a popular casino game that has been captivating gamblers for centuries. It offers a thrilling experience with the potential to win big. However, before diving into the excitement, it is crucial to understand the concept of expected value. Expected value refers to the average amount a player can expect to win or lose per bet in the long run. In the case of roulette, calculating the expected value involves analyzing the probabilities and payouts associated with different bets.
What is the expected value formula?
The formula to calculate the expected value in roulette is quite simple. It can be obtained by multiplying each possible outcome by its probability and summing up the results. Mathematically, it can be represented as follows:
Expected Value = (P1 * X1) + (P2 * X2) + … + (Pn * Xn)
Where P represents the probability of each outcome, and X represents the corresponding payout.
