Convert 12 to 21 Odds to Probability

12 to 21 Odds means that there are 12 chances of one outcome and 21 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 12 A's and 21 B's in 12 to 21 Odds.

12 to 21 Odds can be written as a ratio of 12/21. 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 12 to 21 Odds numbers into the formulas, we get:

(12/(12+21))*100 = 36.36%
(21/(12+21))*100 = 63.64%

Therefore, 12 to 21 Odds converts to the following Probabilities:

36.36% Probability of A

63.64% Probability of B

So instead of saying 12 to 21 Odds, you could say that there is a 36.36% Probability.
