Convert 4 to 81 Odds to Probability

4 to 81 Odds means that there are 4 chances of one outcome and 81 chances of a different outcome.

We will call these different outcomes A and B. Thus, there are 4 A's and 81 B's in 4 to 81 Odds.

4 to 81 Odds can be written as a ratio of 4/81. 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 4 to 81 Odds numbers into the formulas, we get:

(4/(4+81))*100 = 4.71%
(81/(4+81))*100 = 95.29%

Therefore, 4 to 81 Odds converts to the following Probabilities:

4.71% Probability of A

95.29% Probability of B

So instead of saying 4 to 81 Odds, you could say that there is a 4.71% Probability.
