Normal probability curve in statistics

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 … WebA normal curve for any population with N =1, Mean of zero and S of 1 has a probability of unity (1). That is, the total area under the curve is of unit value. This curve is a representative of the probability distribution of populations from which samples are drawn for statistical analyses.
