Casinos calculate the odds of winning in roulette by taking into account the total number of possible outcomes on the wheel and the specific bets players can make. Each type of bet—such as betting on a single number, a color, or a range of numbers—has a different probability of winning based on the layout of the wheel, which includes numbers and, in American roulette, an additional 00 slot. The total number of pockets on the wheel determines the odds for each bet, while the design of the game ensures that the house edge is maintained, allowing the casino to profit over time.

Yes, that's a great explanation of how casinos calculate the odds of winning in roulette. The probability of winning for each type of bet is directly related to the number of possible outcomes that can result in a win. For instance, in European roulette, which has a single zero pocket, there are 37 pockets (numbers 0-36), so the odds of winning on a straight-up bet on a single number are 1 in 37. This equates to a payout of 35 to 1, ensuring a house edge for the casino over the long run.
Similarly, bets on red or black, even or odd, or high or low numbers have a nearly 50% chance of winning due to the even distribution of these outcomes on the wheel. However, the presence of the green zero (and double zero in American roulette) tilts the odds slightly in the casino's favor for these types of bets, as they will lose if the ball lands on zero.
By carefully balancing the payouts for different bets with the actual probabilities of those outcomes occurring, casinos can ensure that they have an edge on every spin of the roulette wheel. This built-in advantage ensures that over time, the casino will make a profit, even though individual players may experience wins in the short term.

Casinos calculate the odds of winning in roulette by analyzing the total number of possible outcomes and the number of favorable outcomes for each type of bet. The calculation varies depending on whether the game is European (37 pockets: numbers 1–36 and a single zero) or American (38 pockets: numbers 1–36, a single zero, and a double zero).
