A bartender calculates that every night she works, she has a 60% chance of earning more than $275 in tips. Suppose she works 35 nights in a row. Use a normal distribution to approximate the probability that she earns more than $275 in tips on at least 25 of those nights.

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.
