In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes

11 авг. 2023 г. · Let X be a discrete random variable with the binomial distribution with parameters n and p for some n∈N and 0≤p≤1. Then the expectation of X is given by:

Hence, the distribution of X gives the probability that it takes n trials before a success occurs. The only parameter for a geometric r.v. is p. Pr{X = n} = (1 ...

Multiply the number of trials (n) by the success probability (p). This value represents the average or expected number of successes. For example ...

This calculator will tell you the expected value for a binomial random variable, given the number of trials and the probability of success.
