véletlenségi

Veletoznámení is the Hungarian word for randomness or chance. It describes a phenomenon or event that lacks a discernible pattern or predictable outcome. In probability theory, véletlenszerű refers to events that cannot be predicted with certainty, even if all relevant information is known. The outcome of a véletlenszerű event is determined by chance.

Véletlenszerű processes are ubiquitous in nature and human activities. Examples include the decay of radioactive isotopes, the outcome of a coin flip, or the distribution of particles in a gas. In statistics, véletlenszerű sampling is a crucial technique for selecting representative samples from a larger population, allowing for inferences about the population as a whole.

The concept of véletlenszerű is often contrasted with determinism, which posits that all events are causally determined by preceding events. While some argue that true véletlenszerű does not exist and is merely a reflection of our incomplete knowledge, in practical applications, véletlenszerű is treated as a fundamental aspect of reality. Algorithms that generate véletlenszerű numbers are essential in fields such as cryptography, simulations, and gaming. The study of véletlenszerű phenomena falls under the domain of probability and statistics.
