WebRandom variables. and. probability distributions. A random variable is a numerical description of the outcome of a statistical experiment. A random variable that may assume only a finite number or an infinite sequence of values is said to be discrete; one that may assume any value in some interval on the real number line is said to be continuous. WebWhen 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. Hence the value of probability ranges from 0 to 1. Probability has been defined in a varied manner by various schools of thought. Some of which are discussed below.

"WebDec 16, 2024 · There are two statistical interpretations used to tackle a problem: frequentist and Bayesian. Frequentists address the probability as a measure of the frequency of various outcomes of an experiment. For example, if we have a fair coin(50% probability of landing heads) we expect that the half number of experiments will land on heads. " - Statistical probabilities in statistics
