Over and under meaning
Since the combined score of that game was 45, anyone who had bet on "under" won.Contents, initial and final value edit, the goal of a sportsbook is to have an equal value of bets on both sides of the overunder.In theory, this means that the manager could set the value at zero and then re-adjust based on either the number of incoming bets and/or events that influence the potential outcome.In practice, the initial value is based on both quantitative (e.g.Winloss record, average points per game, etc.) and anecdotal information (e.g.Media reports, injury status of players, etc.).
As with other types of bets where the odds of either outcome are meant to be even, the vigorish (or "vig is typically set at or about 5 of the total wager.Using American odds, this will result in both outcomes initially being"d at -110 (i.e.Bettors must risk 110 to win 100).If the amount bet on both outcomes is exactly even, using such odds would result in the sportsbook earning 5 in gross profit for every 110 wagered.Of course, bettors will not necessarily risk the same amount of money on both outcomes every time.In such circumstances, there are two ways a sportsbook can mitigate the risk.
The first is to adjust the O/U while keeping the odds of both at -110.For example, if the O/U for a football game is set.5 and the action heavily favors the "over" then the O/U could be adjusted.5 to encourage bettors to take the "under." The risk.The other method to mitigate risk is to adjust the odds on the initial O/U, which is slightly more complicated but eliminates the risk of being "middled." In the aforementioned example, the "under" could be adjusted to -105 while the.In actual scenarios, even adjustments of -100 (i.e."even money and -120 are common place as sportsbooks typically endeavor to maintain steady margins and minimize risk.
Statistics edit, though this bet is most commonly made with the combined score of the two teams, many other statistics can be used, including: In, american football, a player's or team's total rushing yards or attempts, down conversions (first or third interceptions.In basketball, a player's or team's total assists, blocks, turnovers, steals, etc.In baseball, a player's or team's total number of home runs, RBIs, etc.
