WebbTo find the variance σ 2 σ 2 of a discrete probability distribution, find each deviation from its expected value, square it, multiply it by its probability, and add the products. To find the standard deviation σ of a probability distribution, simply take the square root of variance σ 2 σ 2. The formulas are given as below. WebbProbability distributions can be shown in tables and graphs or they can also be described by a formula. For example, the binomial formula is used to calculate binomial probabilities. The following table shows the probability distribution of a tomato packing plant receiving rotten tomatoes.
