(a) What is the expected number of times that Hulk smashes in one 30 day month? (b) What is the probability that Hulk smashes at least one time in a week? (c) What is the probability that Hulk smashes exactly three times in one week?

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.
