Convert 9 to 21 Odds to Probability

9 to 21 Odds means that there are 9 chances of one outcome and 21 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 9 A's and 21 B's in 9 to 21 Odds.

9 to 21 Odds can be written as a ratio of 9/21. 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 21 Odds numbers into the formulas, we get:

(9/(9+21))*100 = 30.00%
(21/(9+21))*100 = 70.00%

Therefore, 9 to 21 Odds converts to the following Probabilities:

30.00% Probability of A

70.00% Probability of B

So instead of saying 9 to 21 Odds, you could say that there is a 30.00% Probability.
