In my experience, in Baccarat, expected value (EV) helps determine the profitability of different bets by calculating the average win or loss per bet over time. It considers the probability of each outcome and the associated payout. For instance, bets with lower house edges, like the Banker bet, generally have a more favorable EV compared to bets with higher house edges, such as the Tie bet. Thus, EV helps players understand which bets offer better long-term value.
