Convert 21 to 4 Odds to Probability

21 to 4 Odds means that there are 21 chances of one outcome and 4 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 21 A's and 4 B's in 21 to 4 Odds.

21 to 4 Odds can be written as a ratio of 21/4. 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 4 Odds numbers into the formulas, we get:

(21/(21+4))*100 = 84.00%
(4/(21+4))*100 = 16.00%

Therefore, 21 to 4 Odds converts to the following Probabilities:

84.00% Probability of A

16.00% Probability of B

So instead of saying 21 to 4 Odds, you could say that there is a 84.00% Probability.
