Probability is the chance or likelihood that an event will happen. We say that an experiment E (or probability space S) is completely described from the probabilis-tic point of view when, for each elementary event Ei it is given, or it is possible to obtain the corresponding probability pi = P(Ei) In this case Corollary 4 allows to derive the probability of any kind of event A as the sum of the Notes on Probability Allin Cottrell 1 Probability: the classical approach The classical approach to probability, which has roots in the study of games of chance, is based on the assumption that we can identify a class of equiprobable individual outcomes of a random experiment. When an event is certain to happen then the probability of occurrence of that event is 1 and when it is certain that the event cannot happen then the probability of that event is 0. What is the PMF .
