Convert 87 to 21 Odds to Probability

87 to 21 Odds means that there are 87 chances of one outcome and 21 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 87 A's and 21 B's in 87 to 21 Odds.

87 to 21 Odds can be written as a ratio of 87/21. 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 87 to 21 Odds numbers into the formulas, we get:

(87/(87+21))*100 = 80.56%
(21/(87+21))*100 = 19.44%

Therefore, 87 to 21 Odds converts to the following Probabilities:

80.56% Probability of A

19.44% Probability of B

So instead of saying 87 to 21 Odds, you could say that there is a 80.56% Probability.
