There are 20-sided dice (shaped like an icosahedron) where each side has a number from 1 to 20 and all sides are equally likely to come up in a single roll. Suppose that you rolled one of these 20-sided die twice in a row and recorded the number from each roll. Are the events "first roll is a 20" and "total of 2 rolls is exactly 15" independent in this scenario?
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.
