Quizplus · Accepted Answer

The Poisson distribution is appropriate when dealing with the number of occurrences of an event over a specified interval of time or space and when the occurrence or nonoccurrence in any interval is independent of the occurrence or nonoccurrence in any other interval. The binomial distribution is appropriate when dealing with a fixed number of independent trials with only two possible outcomes, whereas the hypergeometric distribution is appropriate when dealing with sampling without replacement from a finite population. The normal distribution is appropriate for continuous random variables with a bell-shaped distribution.
