Convert 13 to 21 Odds to Probability

13 to 21 Odds means that there are 13 chances of one outcome and 21 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 13 A's and 21 B's in 13 to 21 Odds.

13 to 21 Odds can be written as a ratio of 13/21. 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 13 to 21 Odds numbers into the formulas, we get:

(13/(13+21))*100 = 38.24%
(21/(13+21))*100 = 61.76%

Therefore, 13 to 21 Odds converts to the following Probabilities:

38.24% Probability of A

61.76% Probability of B

So instead of saying 13 to 21 Odds, you could say that there is a 38.24% Probability.
