When dealing with the number of occurrences of an event over a specified interval of time or space, the appropriate probability distribution is a _____ distribution.
A) Binomial
B) Poisson
C) Normal
D) Hypergeometric probability

Question

Quizplus · Accepted Answer

The Poisson distribution is appropriate for dealing with the number of occurrences of an event over a specified interval of time or space when the events occur independently and at a constant rate. It is commonly used in fields such as biology, economics, and engineering. The binomial distribution is appropriate for counting the number of successes in a fixed number of independent trials, while the normal distribution is appropriate for continuous variables with a bell-shaped curve. The hypergeometric probability distribution is used to model selecting a sample without replacement from a finite population, which is not the case in the scenario described.
