Question 315491
The odds against an event are 9:8. Find the probability that the event WILL occur.
<pre><b>
Learn these formulas:

ODDS IN FAVOR OF EVENT = SUCCESSES:FAILURES

ODDS AGAINST EVENT = FAILURES:SUCCESSES

PROBABILITY EVENT WILL OCCUR = {{{SUCCESSES/(SUCCESSES+FAILURES)}}}

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

so,

PROBABILITY = {{{SUCCESSES/(SUCCESSES+FAILURES)=8/(8+9)=8/17}}}
