Convert 2 to 21 Odds to Probability

2 to 21 Odds means that there are 2 chances of one outcome and 21 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 2 A's and 21 B's in 2 to 21 Odds.

2 to 21 Odds can be written as a ratio of 2/21. 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 2 to 21 Odds numbers into the formulas, we get:

(2/(2+21))*100 = 8.70%
(21/(2+21))*100 = 91.30%

Therefore, 2 to 21 Odds converts to the following Probabilities:

8.70% Probability of A

91.30% Probability of B

So instead of saying 2 to 21 Odds, you could say that there is a 8.70% Probability.
