Odds of +200 mean you can winR$200 on aR$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%
Odds with a negative (-) symbol indicate the betting favorite. The number that follows the negative symbol (the odds) reveals how much to bet for everyR$100 you want to win. For example, as explained above, if the team you're betting has -110 odds, you need to wagerR$110 to winR$100.
