The probability theory is the section of mathematical science studying regularities of the accidental phenomena. A subject of studying probability theory is the research of probabilistic regularities of the accidental (uniform) mass phenomena. The methods revealed in probability theory found broad application in the majority of modern sciences and various fields of activity of the person.
Especially widely the probability theory is applied to a research of the natural phenomena. All processes proceeding in the nature, all physical phenomena to a degree do not do without presence of an element of chance. Kind of an experiment, kind of precisely was definitely not conducted results of empirical researches at repeated carrying out an experiment would be recorded, results will differ from secondary data.
At the solution of many tasks their outcome depends on a large number of factors which are difficult for registering or considering, but they render huge value on the end result. Sometimes the quantity of these minor factors are a lot of, and they have so great influence that cannot simply be considered by their classical methods. So, for example, it is tasks on definition of the movement of planets of the Solar system, weather forecasts, length of a jump of the athlete, probability of a meeting of the acquaintance on the way on service and various situations in stock exchange.
The probability theory is applicable in robotics. For example, the certain automated device (primary preparation of the robot) carries out certain calculations. While it conducts calculations, outside systematically influence it various hindrances insignificant for a system, but affecting results of work. The task of the engineer is in defining with what frequency there will be a mistake imposed by external hindrances. Also by methods of probability theory it is possible to develop an algorithm for data of an error of calculation to a minimum. Tasks of this sort very often meet in physics and when developing new types of the equipment. They demand thorough study not only the main regularities of these phenomena explaining the main lines in their general concepts, but also the analysis of the accidental distortions and indignations connected with action of minor factors which give to the result of experience in the set conditions that element of chance (uncertainty).
