Probability rules in statistics

WebbIn probability theory and statistics, a probability distribution is the mathematical function that gives the probabilities of occurrence of different possible outcomes for an experiment. It is a mathematical description of a random phenomenon in terms of its sample space and the probabilities of events (subsets of the sample space).. For instance, if X is used to … WebbProbability is represented by a numerical value between 0 and 1 which describes how likely an event is to happen. A probability of 0 indicates that it is impossible for an event to happen while a probability of 1 means that it is sure to happen. Probability is also often expressed using percentages.
