Convert 18 to 91 Odds to Probability

18 to 91 Odds means that there are 18 chances of one outcome and 91 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 18 A's and 91 B's in 18 to 91 Odds.

18 to 91 Odds can be written as a ratio of 18/91. 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 18 to 91 Odds numbers into the formulas, we get:

(18/(18+91))*100 = 16.51%
(91/(18+91))*100 = 83.49%

Therefore, 18 to 91 Odds converts to the following Probabilities:

16.51% Probability of A

83.49% Probability of B

So instead of saying 18 to 91 Odds, you could say that there is a 16.51% Probability.
