Probability is defined in terms of either the long‐term frequency of events, as model based or as a subjective measure of the certainty of an event happening. Examples of each type are given. The concepts of independent events and mutually exclusive events are discussed. Several theoretical statistical distributions, such as the Binomial, Poisson and Normal are described. The properties of the Normal distribution and its importance are stressed and its use in calculating reference intervals is also discussed.
