Poisson distribution

The Poisson distribution has been explained in an earlier section of this chapter. In a nutshell, the Poisson distribution is a binomial distribution with an infinitely large number of samples, so large that the discrete nature of the binomial distribution gives way to the Poisson distribution. The Poisson distribution also deals with the probability of the occurrence of events. But rather than thinking in terms of the probability of the occurrence of the event in each trial, we think in terms of time intervals and ask ourselves how many times the event of interest would occur in that time interval. The parameter also moves from the probability of success for each trial to the number of successes in a given time interval. ...
