3. A student is trying to estimate how many hours (rounded to the nearest hour) an instructor might spend between 7pm and midnight playing video games. They create the following probability model: Hours 1 2 3 4 Probability .32 .15 .27 .14 .07 a. What is the probability they play for 5 hours? b. What is the probability they play for an even number of hours?
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.
