25 to 1 Odds means that there are 25 chances of one outcome and 1 chances of a different outcome.
We will call these different outcomes A and B. Thus, there are 25 A's and 1 B's in 25 to 1 Odds.
25 to 1 Odds can be written as a ratio of 25/1. 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 25 to 1 Odds numbers into the formulas, we get:
(25/(25+1))*100 = 96.15%
(1/(25+1))*100 = 3.85%
Therefore, 25 to 1 Odds converts to the following Probabilities:
96.15% Probability of A
3.85% Probability of B
So instead of saying 25 to 1 Odds, you could say that there is a 96.15% Probability.
