Suppose you commit a crime. The way the judge is going to set your sentence is by pulling a number out of a hat. You know that there are ten 1-year sentences, five 2-year sentences and one 20-year sentences in the hat. What is the variance of the expected number of years you will spend in jail?
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.
