We wish to determine if using the newly styled 8 sided die would be fair. Fair meaning that every single one of the 8 faces will have a ⅛ (.125) probability of landing face-up everytime the die is rolled. Suppose the die is tossed 80 times, We are expecting the frequency to be 10 (each number on the die faces up 10 times) Ho: The die is fair Ha: The die is not fair
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.

Suppose the die is tossed 80 times,
We are expecting the frequency to be 10 (each number on the die faces up 10 times)
Ho: The die is fair
Ha: The die is not fair
