Importance of Probability

The importance of probability is that, through this mathematical resource, it is possible to adjust as accurately as possible the imponderables due to chance in the most varied fields of both science and life daily.

Indeed, probability It is a strategy by which an attempt is made to estimate the frequency with which a certain result is obtained within the framework of an experience in which all possible results are known. Thus, the most traditional example consists of defining the prevalence of obtaining a number when throwing a dice. Out of six possible outcomes (all heads), it is only possible to achieve one number for each time the die is thrown. In this case, the probability can be expressed as one in six, one sixth, one sixth, or, in precise mathematical terms, 0.16 or 16%.

The probability theory, especially in the framework of more complex systems, is applied in various areas of knowledge, such as exact Sciences (statistics, pure and applied mathematics, physics, chemistry, astronomy), the

social Sciences (sociology, Social psychology, economics), astronomy, meteorology and, especially more recently, biomedicine.

The essential importance of applying the calculation methods of probability lies in its ability to estimate or predict events. The greater the amount of data available to calculate the probability of an event, the more accurate the calculated result will be. Given the complexity of the systems in which probability theory is usually applied, computer models and statistics of great elaboration, which would be impossible without counting on the modern technological resources related to the computing.

A good example of its everyday applicability is provided by the analyzes of trade in commodities (raw materials) in current international relations. Given that a large part of the factors involved in estimating production are random (winds, environmental humidity, solar exposure, actual workforce, local economic and financial conditions, regional political vicissitudes, among others), the probability theory It is of great importance, since it tries to adjust in mathematical concepts what will be the future of the events to calculate, for example, the final production of cereals, fossil fuels and other resources of a Geographic area.

Therefore, probability is an essential tool in planning strategic of the social movements, economic and labor of the entire community.
