The odds against an event are 9:8. Find the probability that the event WILL occur.

Learn these formulas:

ODDS IN FAVOR OF EVENT = SUCCESSES:FAILURES

ODDS AGAINST EVENT = FAILURES:SUCCESSES

PROBABILITY EVENT WILL OCCUR = 

So since odds against are 9:8, then FAILURES = 9 and SUCCESSES = 8

Rule: "odds against A" = P(not A)/P(A)

P(not A) = 9/17
---
P(A) = 8/17
