👉 Gambling math is based on the concept of expected value, which represents the average outcome of a game over many repetitions. In gambling, each bet has an inherent probability of winning or losing, and the house edge is built into the game to ensure a profit for the casino over time. For instance, in a classic game of roulette, the house edge is typically around 5.26% for European roulette (with a single zero) or 5.26% for American roulette (with both zeroes). This means that if you bet $100, you can expect to win back approximately $102.26 on average after accounting for the house edge. The math shows that despite short-term wins, over time, the house will always win more than players, making gambling mathematically unfavorable.
