Question 3.2 3.2 A call centre receives calls that can be described by the Poisson process. The average rate at which calls received is 5 calls per minute. 3.2.1 Determine the probability that the call centre will receive exactly 3 calls. 3.2.2 Calculate the likelihood that the call centre will receive at least 3 calls per 2 minitee 3.2.3 Determine the standard deviation of the call centre receiving calls per 5 minutes.

Contingency Table

A contingency table can be defined as the visual representation of the relationship between two or more categorical variables that can be evaluated and registered. It is a categorical version of the scatterplot, which is used to investigate the linear relationship between two variables. A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

Binomial Distribution

Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
