Convert 21 to 78 Odds to Probability

21 to 78 Odds means that there are 21 chances of one outcome and 78 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 21 A's and 78 B's in 21 to 78 Odds.

21 to 78 Odds can be written as a ratio of 21/78. 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 21 to 78 Odds numbers into the formulas, we get:

(21/(21+78))*100 = 21.21%
(78/(21+78))*100 = 78.79%

Therefore, 21 to 78 Odds converts to the following Probabilities:

21.21% Probability of A

78.79% Probability of B
