The Poisson distribution can be used to approximate the binomial probabilities when the number of trials n is large and at the same time the probability P is:
A)also large.
B)one.
C)small.
D)equal to λ.

Question

Quizplus · Accepted Answer

The Poisson distribution is a good approximation for the binomial distribution when the number of trials is large and the probability of success is small. Therefore, choice C is the best option as it states that P is small, which fits the criteria for when the Poisson distribution can be used to approximate the binomial probabilities.
