A Poisson probability distribution of a discrete random variable gives the probability of a number of events occurring in a fixed interval of time, if these events happen at a known average rate and independently of the time since the last event. s = Standard deviation of the given normal distribution. WABT presents the procedure to calculate the probability of Bayes' Theorem through the simulation of data about the supply of products. We now look at each rule in detail. Probability of an event to happen lies between 0 and 1, where, 0 indicates impossibility and 1 indicates certainty. Some events are truly random. This leads us to various statistical distributions along with their Excel functions which are then used to model or approximate business processes. Mean a + b. Variance b2. The following formula is used for Normal distribution- i. y = the computed height of an ordinate at a distance of X from the mean. Applications of Poisson distribution.
