If the odds of success are 3 to 2, what is the probability of success?

Odds express the ratio of successful outcomes to unsuccessful ones. If the odds of success are 3 to 2, there are 3 successes for every 2 failures. The probability of success is the fraction of all outcomes that are successful: 3/(3+2) = 3/5 = 0.60. So the probability is 0.60. For reference, 0.50 corresponds to 1 to 1 odds, 0.40 to 2 to 3 odds, and 0.75 to 3 to 1 odds.
