And the odds against the same event occurring are: Odds (against)E = unfavorable outcomes favorable outcomes = 2 1 Odds (against) E = unfavorable outcomes favorable outcomes = 2 1.
The odds are the ratios that compare the number of ways the event can occur with the number of ways the event cannot occurr. The odds in favor - the ratio of the number of ways that an outcome can occur compared to how many ways it cannot occur. Odds in favor = Number of successes: Number of failures.
