Probability: Probability is a measure of how likely an event is to occur. It is expressed as a number between 0 and 1, where 0 represents impossibility and 1 represents certainty. See also Knowledge, Certainty, Likelihood, Chance, Probability theory, Probability distribution, Probability functions._____________ Annotation: The above characterizations of concepts are neither definitions nor exhausting presentations of problems related to them.

Richard Feynman on Probability - Dictionary of Arguments I 86 Def Probability//Feynman: of a particular result of an observation: our estimate of the most probable fraction of a number of repeated observations giving the particular result. I 87 P(A) = NA/N. (s) NA: desired N: all Probability/Feynman: absurd: e.g. what is the probability of a ghost in this house? There is no repetition here. N and NA are not numbers based on actual observations. NA is our best guess of what would happen. >Subjective probability, >Chance, >Conditional probability, cf. >Bayesianism, >Relative frequency. I.e. probability is dependent on our knowledge and common sense. Probabilities change as our knowledge changes. I 551 Probability/Feynman: of course, there is no probability that gas atoms will go in a certain direction, because a certain direction is too exact. Therefore, we must speak of a standard "size": As many molecules pass through any surface as through any other surface of equal size on the sphere. >Measurements, >Method, >Generalization, >Idealization. _____________ Explanation of symbols: Roman numerals indicate the source, arabic numerals indicate the page number.
