Event

The basic concept in the theory of probability and statistics, denoting the realisation of some potentiality in a certain set of conditions. If, given the set of conditions in question, the event happens of necessity, it is called authentic. If it is known that, given the same conditions, the event cannot happen, it is called impossible. An event which may or may not happen is called chance.

Single chance events can be characterised only qualitatively. Mass chance events may be characterised qualitatively and also quantitatively by calculating the probability of a given event in a definite set of conditions. Thus the probability P of an event A is equal to the ratio of the number of tests favourable to the event A (m), to the total number of tests n: P(A) = m/n.
