How do you calculate the odds of winning a bet?

For an underdog, the equation is 100/(odds +100) x 100. So a +150 underdog would be calculated as 100/(150 + 100) x 100. That equals 40, meaning a +150 underdog has an implied win probability of 40 percent. For fractional odds, the equation is denominator/(denominator + numerator) x 100.

What is the formula of calculating winning odds?
