A probabilistic system is one where events and occurrences cannot be predicted with precise accuracy. It is contrasted by a deterministic system in which all events can be predicted with certainty.
Know MoreIn a probabilistic system, unlike in a deterministic system, what has just occurred is not always an accurate predictor of what will transpire next. The weather, for example, is a probabilistic system, in that future events can only be imperfectly predicted.
The theory of probabilistic systems by extension leads to probabilistic analysis and forecasting. A probabilistic system must be analyzed according to the various possible outcomes and their relative probability of occurrence.

Full Answer >Statistics allow people to analyze surveys, experiments and other data, but they are easy to misrepresent or to use to mislead others. Statistical data is essential to the scientific method. It also helps companies, governments and other entities make decisions.
Full Answer >The kinetic theory of matter, also called the kinetic particle theory or simply the kinetic theory, differentiates the three states of matter based on their arrangement and physical characteristics as well as their distinct patterns of movement. There are three primary states of matter under which particles fall: solid, liquid and gas. These states are interrelated and exist simultaneously in the atmosphere, but contain important distinguishing characteristics that set them apart from one another.
