Convert 18 to 1 Odds to Probability

18 to 1 Odds means that there are 18 chances of one outcome and 1 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 18 A's and 1 B's in 18 to 1 Odds.

18 to 1 Odds can be written as a ratio of 18/1. 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 1 Odds numbers into the formulas, we get:

(18/(18+1))*100 = 94.74%
(1/(18+1))*100 = 5.26%

Therefore, 18 to 1 Odds converts to the following Probabilities:

94.74% Probability of A

5.26% Probability of B

So instead of saying 18 to 1 Odds, you could say that there is a 94.74% Probability.
