Convert 20 to 9 Odds to Probability

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

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

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

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

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

68.97% Probability of A

31.03% Probability of B

So instead of saying 20 to 9 Odds, you could say that there is a 68.97% Probability.
