Binomial, Poisson, and Multinomial Distributions

First, we will talk about binomial probabilities, how to compute their cumulatives, and the mean and standard deviation. Then, we will introduce the Poisson probability formula, define multinomial outcomes, and discuss how to compute probabilities by using the multinomial distribution.

Question 1 out of 1.
The mean number of defective products produced in a factory in one day is 21. What is the probability that in a given day there are exactly 12 defective products?
