The over/under bet is a popular option at most sportsbooks. These bets are based on the total number of points scored in a game and can be fun to place. However, be aware that these bets do not guarantee a winner. In fact, they can often be lost.

When calculating the expected value of a bet, it is important to take into account the margin of error. This will help you determine whether the sportsbook is over- or underpaying bettors. The odds of a team winning against the spread are typically higher than the odds of them beating the point spread, so the oddsmakers will try to balance action on both sides to avoid heavy losses.
