1. Probabilitynoun

   Likelihood; appearance of truth; evidence arising from the preponderation of argument: it is less than moral certainty.

   Etymology: probabilitas, Lat. probabilité, Fr. from probable.

   Probability is the appearance of the agreement or disagreement of two ideas, by the intervention of proofs, whose connection is not constant; but appears for the most part to be so. John Locke.

   As for probabilities, what thing was there ever set down so agreeable with sound reason, but some probable shew against it might be made? Richard Hooker, Preface.

   If a truth be certain, and thwart interest, it will quickly fetch it down to but a probability; nay, if it does not carry with it an impregnable evidence, it will go near to debase it to a downright falsity. Robert South, Sermons.

   Though moral certainty be sometimes taken for a high degree of probability, which can only produce a doubtful assent; yet it is also frequently used for a firm assent to a thing upon such grounds, as are fit fully to satisfy a prudent man. John Tillotson, Sermons.

   For a perpetual motion, magnetical virtues are not without some strong probabilities of proving effectual. John Wilkins.

1. Probability

   Probability is the branch of mathematics concerning numerical descriptions of how likely an event is to occur, or how likely it is that a proposition is true. The probability of an event is a number between 0 and 1, where, roughly speaking, 0 indicates impossibility of the event and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur. A simple example is the tossing of a fair (unbiased) coin. Since the coin is fair, the two outcomes ("heads" and "tails") are both equally probable; the probability of "heads" equals the probability of "tails"; and since no other outcomes are possible, the probability of either "heads" or "tails" is 1/2 (which could also be written as 0.5 or 50%). These concepts have been given an axiomatic mathematical formalization in probability theory, which is used widely in areas of study such as statistics, mathematics, science, finance, gambling, artificial intelligence, machine learning, computer science, game theory, and philosophy to, for example, draw inferences about the expected frequency of events. Probability theory is also used to describe the underlying mechanics and regularities of complex systems.

1. probability

   Probability is a mathematical measure that quantifies the likelihood or chance of a particular event or outcome occurring. It is expressed as a number between 0 and 1, where 0 indicates that the event will not occur, and 1 indicates that the event is certain to occur. It is often expressed as a fraction, percentage, or decimal. Probability can be theoretical, based on reasoning and analysis, or empirical, based on observed data.

1. Probability

   Probability is a measure or estimation of how likely it is that something will happen or that a statement is true. Probabilities are given a value between 0 and 1. The higher the degree of probability, the more likely the event is to happen, or, in a longer series of samples, the greater the number of times such event is expected to happen. These concepts have been given an axiomatic mathematical derivation in probability theory, which is used widely in such areas of study as mathematics, statistics, finance, gambling, science, artificial intelligence/machine learning and philosophy to, for example, draw inferences about the expected frequency of events. Probability theory is also used to describe the underlying mechanics and regularities of complex systems.
