Sports betting is the activity of predicting sports results and placing a wager on the outcome.
Sports bettors place their wagers either legally, through a bookmaker/sportsbook, or illegally through privately run enterprises referred to as “bookies”. The term “book” is a reference to the books used by wage brokers to track wagers, payouts, and debts. Many legal sportsbooks are found online, operated over the Internet from jurisdictions separate from the clients they serve, usually to get around various gambling laws (such as the Unlawful Internet Gambling Enforcement Act of 2006 in the United States) in select markets, such as Las Vegas, or on gambling cruises through self-serve kiosks.[1] There are different types of legalized sports betting now such as game betting, parlays props and future bets. They take bets “up-front”, meaning the bettor must pay the sportsbook before placing the bet. Due to the nature of their business, illegal bookies can operate anywhere but only require money from losing bettors and do not require the wagered money up front, creating the possibility of debt to the bookie from the bettor. This creates a number of other criminal elements, thus furthering their illegality. (來源 )
例如，如果球隊A的勝利賠率為1.50，投注者下注100元，如果球隊A勝利，將獲得100 x 1.50 = 150元的獲利，淨獲利為150 – 100 = 50元。
值得注意的是，賠率越低，代表該球隊被認為勝算越大；而賠率越高，則代表該球隊的勝算較低。
Odds for different outcomes in single bet are presented either in European format (decimal odds), UK format (fractional odds), or American format (money line odds). European format (decimal odds) are used in continental Europe, Canada, and Australia. They are the ratio of the full payout to the stake, in a decimal format. Decimal odds of 2.00 are an even bet. UK format (fractional odds) are used by British bookmakers. They are the ratio of the amount won to the stake – the solidus “/” is pronounced “to” for example 7/1 “seven to one”. Fractional odds of 1/1 are an even bet. US format odds are the amount won on a 100 stake when positive, and the stake needed to win 100 when negative. US odds of 100 are an even bet. (來源 )
