Bernoulli distribution:

Generalized random

experiment of two

outcomes

Binomial distribution:

Number of successes in n

experiments (number of

defective items in a batch)

Poisson distribution:

                                                                            Stochastic arrival processes;

λ: average number of

arrivals per time unit

Geometric distribution:

P (x) = p (1-p)^x
