[8] Suppose that the number of customers that arrive at an AT&T wireless store can be modeled by a Poisson Distribution, with a mean of 3 customer arrivals every hour. Suppose that the store manager needs to run out of the store for a period of 10 minutes. (a) Compute the probability that no customers will arrive at the AT&T store in that 10-minute period. (b) Compute the probability that three or more customers arrive in that 10-minute period.

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.
