Experimental Definitions

experiment

An experiment is a planned operation carried out under controlled conditions or in a way that can be repeated.

outcome (or simple event)

An outcome (or simple event) is the exact result of an experiment usually written down to form the statistical data.

Event:

a certain set of outcomes under considerations. Usually denoted with a capital letter, like E.

Probability

The probability of event E occurring is written P(E). P(E) = 1, if we are certain that the event will occur. P(E) = 0, if event E cannot happen. P(E)= 0.5 =50% if event E is equally likely to occur or not occur.

Sample Space

The collection of all possible outcomes of the experiment. Often denoted by the Greek capital letter omega, Ω. Our textbook uses capital S.
