probability/prob·a·bil·i·ty/ the likelihood of occurrence of a specified event, often represented as a number between 0 (never) and 1 (always) corresponding to the long-run frequency at which an event occurs in a sequence of random independent trials as the number of trials approaches infinity.
probabilityStatistics p value The likelihood that an event will occur by chance alone, and given a value between 0–impossible and 1–certain; the higher the p value, the more likely that 2 or more sets of overlapping variables occurred randomly–ie, the less the likelihood that the 2 events are associated; the lower the p value, the greater is the likelihood that the events are not random associations–counterintuitive, but think it out in a dark quiet room, you'll get it. See Conditional probability, Empirical probability, Gaussian probability, Personal probability, Prior probability, Theoretic probability Vox populi An expression of the likelihood that a specific event will occur.
probabilitythe likelihood that a given event will occur. Probability is expressed either as values between zero (complete certainty that an event will not occur) and 1.0 (complete certainty that an event will occur) or percentage values between 0 and 100. Probability is used widely in SIGNIFICANCE tests.
n 2. a mathematic ratio of the number of times something will occur to the total number of possible occurrences.
Patient discussion about probability
Q. What is the likelihood of my depression returning? I have a history of severe depression. My mom is very against medication and counseling, and reluctantly allowed me to go on the lowest dosage of zoloft. It helped, but now she wants me to go off of it and stop going to my doctor. My fear is that my depression will return. What are the chances of my depression returning, and how can I handle it if and when it does?
