For example, if the odds for a particular team to win a championship are +500, this means that a bettor would receive a payout of $500 for every $100 they wagered if that team goes on to win the championship.

Odds of +200 mean you can win $200 on a $100 bet, but there's no quick way to determine the implied winning probability. If these odds appeared as fractional odds 2/1 you could quickly solve for the implied winning probability using this formula: Decimal / (Numerator + Denominator) x 100%
