To find odds you must first know how to determine the probability of success and the probability of failure. (The ^odds given at horse races and at table games and at Casinos are always odds against unless otherwise specified.) Example: A single 6 sided dice is rolled one time and the number that is face up is recorded.
The absolute risk is the probability of an event in a sample or population of interest. The relative risk (RR) is the risk of the event in an experimental group relative to that in a control group. The odds ratio (OR) is the odds of an event in an experimental group relative to that in a control group.

This simplistic dictionary definition of the probable quality attached to an event is unanimously accepted in current speech. Far from standing for a rigorous definition, this enunciation still gives evidence for the quantitative and measurement aspect of the probability concept because the chance of an event occurring is
Jan 1, 2016 · The odds ratio is a measurement of association that compares the odds of an event of those exposed to the odds of an event in those unexposed. It serves to determine the relation between...

Odds are the probability of an event occur-ring divided by the probability of the event not occurring. An odds ratio is the odds of the event in one group, for example, those exposed to a drug, divided by the odds in another group not exposed. Odds ratios always ex-aggerate the true relative risk to some degree.

The odds of an event is the ratio of the probability of an event occurring to the probability of the event not occurring (π 1 − π), and the OR describes the change in odds for a change in a predictor; it is a ratio of ratios.
