Convert 9 to 20 Odds to Probability

9 to 20 Odds means that there are 9 chances of one outcome and 20 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 9 A's and 20 B's in 9 to 20 Odds.

9 to 20 Odds can be written as a ratio of 9/20. 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 9 to 20 Odds numbers into the formulas, we get:

(9/(9+20))*100 = 31.03%
(20/(9+20))*100 = 68.97%

Therefore, 9 to 20 Odds converts to the following Probabilities:

31.03% Probability of A

68.97% Probability of B

So instead of saying 9 to 20 Odds, you could say that there is a 31.03% Probability.
