Suppose customers arrive to a 7–11 convenience store according to a Poisson process with rate 10 per hour. What are the probabilities of (a) no customers in an hour; (b) exactly 5 customers in an hour; (c) exactly 10 customers in two hours; and (d) at least two customers in half an hour?
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.
