Basic meaning of probability

The old name of probability.

Probability refined edition

• The old name of probability.
• Probability, also known as "probability", "probability" and "probability", refers to the probability of an event. Under the same conditions, the change and development of an event often have several different possibilities. This event is called "random event", and this phenomenon is called "random phenomenon". The probability of occurrence of different random events is different. Probability is the quantity used to indicate the probability of occurrence of random events. The classical definition of probability: the probability of the occurrence of an event A is the ratio of the possible situation of A to all possible situations. Frequency definition of probability: the probability of occurrence of an event A is equal to the frequency of occurrence of A in several tests. Its formula is as follows: probability of occurrence of A=(number of occurrences of A/total number of tests) In other words, under the same conditions, if there are only two possibilities of occurrence of an event, Then the possible occurrence times of any one of these events will account for half of the total test times. The limit of the relative value of the number of occurrences of a phenomenon (event) is known as the probability. Probability indicates the summation of a large number of repeated random phenomena. For example, for a gas composed of a large number of molecules, the kinetic energy of each molecule is random, but its overall performance temperature is determined. As a branch of mathematics, probability theory is a science that systematically studies probability, and the theory of inductive reasoning using probability theory as a tool produces probability logic. Therefore, probability or probability is a basic concept in probability logic, which is different from the inductive method of experience and is an inductive method of applied mathematical methods. Probability logic comes into being as a direct continuation of inductive logic. Since the conclusion of inductive logic and the conclusion of hypothetical deduction are both probable, it is necessary to estimate the probability of a certain conclusion from the quantitative aspect and introduce the precise probability method formulated in mathematics into logic. Probability has been discussed in two chapters in the inductive part of A System of Logic by John Stuart Mill (1806-1873), a British utilitarian. George Boole (1815-1864), an English mathematician and logician, proposed the logical explanation of probability, and advocated that the probability of judging relevant events should be investigated instead of the probability of events themselves. The former Soviet mathematician A.H. Kormoropov (1903~) put forward the axiomatic definition of probability, and elaborated the principle of the theory of random process without aftereffect in his book [Analytical Method of Probability Theory], which has quite an impact on the development of probability theory. Since then, Rudolf Carnap (1891-1970), a logical positivist, emphasized that the concept of probability in inductive logic should be divided into: the logical concept of probability and the statistical concept of probability; In addition, Hans Reichenbach (1891-1953) replaced the concept of relative frequency (that is, the concept of "statistical probability") with the concept of purely analytical "logical probability", and constructed and developed the logical axiom system of probability based on the concept of "logical probability", providing a set of precise logical tools for the prediction of probability under certain special circumstances-- Author: Liu Guijie
• If a randomized experiment is repeated, the probability of occurrence of event (A) is [P (A)], which is the ratio of the number of occurrences of event A (fA) to the total number of trials (n), that is, P (A)=fA/n.
• The number of opportunities or possibilities. [Sentence] With the increase of the number of places admitted, the probability of each examinee getting on the list has increased a lot.
• The number of opportunities or possibilities. Also called "probability" or "probability".
