Probability of an event definition

Webb10 sep. 2024 · The probability of an event has a very specific meaning in mathematics. The probability of an event E is the number of different outcomes resulting in E divided by the total number of equally likely outcomes. In mathematical symbols, P ( E) = number of different outcomes resulting in E total number of equally likely outcomes.

4.1: Probability Experiments and Sample Spaces

Defining all subsets of the sample space as events works well when there are only finitely many outcomes, but gives rise to problems when the sample space is infinite. For many standard probability distributions, such as the normal distribution, the sample space is the set of real numbers or some subset of the real numbers. Attempts to define probabilities for all subsets of the real numbers run into difficulties when one considers 'badly behaved' sets, such as those that … WebbImpossible events have a probability of 0, and events that are certain to happen have a probability of 1.
