Convert 21 to 15 Odds to Probability

21 to 15 Odds means that there are 21 chances of one outcome and 15 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 21 A's and 15 B's in 21 to 15 Odds.

21 to 15 Odds can be written as a ratio of 21/15. Instead of a ratio, Probability shows the percent chance of the outcomes A and B.

The two formulas to convert Odds to Probabilities are as follows

(A/(A+B))*100 = A%
(B/(A+B))*100 = B%

When we plug the 21 to 15 Odds numbers into the formulas, we get:

(21/(21+15))*100 = 58.33%
(15/(21+15))*100 = 41.67%

Therefore, 21 to 15 Odds converts to the following Probabilities:

58.33% Probability of A

41.67% Probability of B

So instead of saying 21 to 15 Odds, you could say that there is a 58.33% Probability.
