You can put this solution on YOUR website! The odds against Lighting winning the Kentucky Derby are 9:2. Find the probability that Lighting wins.
-----------------------
Odds AGAINST event "E" = [P(not E)]/[P(E)]
---------------------------------------------
Equation:
P(against winning) = P(not winning)/P(winning) = 9:2
---
P(not winning) = 9/11: P(winning) = 2/11
