A probability of 0.8 has odds of 0.8/(1 − 0.8) = 4, or 4 to 1. If the odds are 2 (or 2-to-1), then the probability is 2/(1 + 2) = 2/3. Higher odds indicate higher probabilities and greater likelihood. Note that although the probability cannot be outside the range from...
Interpretation of odds ratios does take practice (like any skill), and the important aspect to appreciate is that the odds ratio is a scaling factor applied to the number of ‘successes’ in a baseline case for every ‘failure’, irrespective of how many ‘successes’ there actually were. No...

Probability is the branch of mathematics that considers the probable results of specified actions collectively with the outcomes' proportionate likelihoods and distributions. In common practice, the word "probability" means the chance that a specific event or group of events will occ...
What are the odds in favor of being dealt a given poker hand? There are C(52,5) = 2598960 different poker hands and each of them is dealt with the same probability. [The choice number C(52,5) is pronounced "52 choose 5" and is equal to the number of ways 5 objects can be ...
Results Fourteen randomized controlled trials that included 3828 patients met the inclusion criteria and were analyzed with outcomes categorized as short term (≤3 months) or long term (>3 months). Three trials showed no overall effect of diagnostic tests on illness worry (odds ratio, 0.87 [95%...

(whereby the area on the wheel is adjusted to correspond to the probability of being correct), relative frequency estimates (e.g., “for 100 cases about which I was this sure, I would expect about 60 to be correct”), and odds judgments (e.g., “I would assign it odds of 3 to ...
