Convert 1 to 18 Odds to Probability

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

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

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

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

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

5.26% Probability of A

94.74% Probability of B

So instead of saying 1 to 18 Odds, you could say that there is a 5.26% Probability.
