Decimal odds explained\n\n For example, aR$100 bet made at decimal odds of 3.00 would returnR$300 ($100 x 3.00): $200 in profit and the originalR$100 amount risked. AR$100 bet made at decimal odds of 1.50 would returnR$150:R$50 in profit and the originalR$100 amount risked.
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%
