In statistics, probability refers to the chances of some event happening It is calculated as PROBABILITY P(event) = (# desirable outcomes) / (# possible outcomes) For example, suppose we have four red balls and one green ball in a bag If you close your eyes and randomly select a ball, the probability that you choose a green ball is calculated as P(green) = 1 / 5 = 02 The odds⇒ Odds in Favor of an Event = P(Event) P(Event c) Probabilities against and for the event can be used as the antecedent and consequent of the ratio representing the odds against an event in place of unfavorable and favorable choices Odds against an Event Odds against an Event =The Ask Dr Math forum has several entries on odds versus probability Summarizing, one way to conceptualize (nontechnically) the probability of an event is the number of ways that an event can occur divided by the total number of possible outcomes The probability of heads in a fair coin flip is 1/2 (50 percent) The probability of drawing a red card from a standard deck of

"Odds" refers to the probability of occurrence of an event/probability of the event not occurring At first glance, though these two concepts seem similar and interchangeable, there are important differences that dictate where the use of either of these is appropriate Let us look at the hypothetical example of a randomized trial comparing endoscopic sclerotherapy (n = 65) versusConversely, if odds are very small (1/1000), probability will also be very small, close to 0 Probability/Odds Conversion Converting probabilities into odds, we simply divide the probability by 1 less the probability, eg, if the probability is 25% (025), the odds are 025/075, which can also be expressed as 1 to 3 or 1/3 or 0333 OddsProbability vs Odds Real life is full of incidents with uncertainty The terms probability and odds measure one's belief in the occurrence of a future event It may confuse since both 'Odds' and 'probability' are related to the potential that event occurs However, there is a difference Probability is a broader mathematical concept However odds is another method for
