The odds against a horse winning a race are 6 to 5. What is the probability
of the horse winning the race?
Conversion formulas for ODDS IN FAVOR and AGAINST
to and from PROBABILITY
1. If odds in favor of event E are "a to b" then P(E) =
2. If odds against event E are "a to b" then P(E) =
3. If P(E) = , then ODDS in favor of event E = "a to b-a"
4. If P(E) = , then ODDS against event E = "(b-a) to a"
We need formula 2:
2. If odds against event a horse winning a race are "6 to 5"
then P(horse winning the race) = =
