What is a totals (over/under) bet?

A totals bet is a wager on whether the combined final score of both teams will be over or under a number set by the sportsbook. For example, if the total is 47.5, you bet whether the final combined score will be 48+ (over) or 47 or fewer (under). It does not matter who wins — only the combined scoring counts. Totals typically also pay at -110.
