Tõenäosuus

Tõenäosus is the Estonian word for probability. It is a fundamental concept in mathematics and statistics that quantifies the likelihood of an event occurring. Tõenäosus is expressed as a number between 0 and 1, inclusive. A tõenäosus of 0 means the event is impossible, while a tõenäosus of 1 means the event is certain.

The calculation of tõenäosus typically involves comparing the number of favorable outcomes to the total number of possible outcomes. For example, if you roll a fair six-sided die, there are six possible outcomes (1, 2, 3, 4, 5, 6). The probability of rolling a 3 is 1/6, as there is one favorable outcome (rolling a 3) out of six total possibilities.

Tõenäosus plays a crucial role in various fields, including science, engineering, finance, and decision-making. It allows for the analysis of uncertainty and the prediction of future outcomes based on available data. Concepts such as conditional probability, independent events, and random variables are all integral to understanding and applying tõenäosus. The study of tõenäosus forms the basis of probability theory, a branch of mathematics concerned with chance occurrences.
