WebIn 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 … WebOct 21, 2024 · Then the binomial can be approximated by the normal distribution with mean μ = n p and standard deviation σ = n p q. Remember that q = 1 − p. In order to get the best approximation, add 0.5 to x or subtract 0.5 from x (use x + 0.5 or x − 0.5 ). The number 0.5 is called the continuity correction factor and is used in the following example.
