Write down a precise sum expression for the probability that the first five rolls give a three at most two times. b. Calculate the probability that the first three does not appear before the fifth roll. c. Calculate the probability that the first three appears before the twentieth roll but not before the fifth roll.
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.
