Convert 12 to 30 Odds to Probability

12 to 30 Odds means that there are 12 chances of one outcome and 30 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 12 A's and 30 B's in 12 to 30 Odds.

12 to 30 Odds can be written as a ratio of 12/30. 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 30 Odds numbers into the formulas, we get:

(12/(12+30))*100 = 28.57%
(30/(12+30))*100 = 71.43%

Therefore, 12 to 30 Odds converts to the following Probabilities:

28.57% Probability of A

71.43% Probability of B

So instead of saying 12 to 30 Odds, you could say that there is a 28.57% Probability.
