Suppose that you are looking for a student at your college who lives within five miles of you. You know that 40% of the 248 students do live within five miles of you. You randomly contact students from the college until one says he or she lives within five miles of you. Find the probability it will take. A. 5 of them until one says he or shhe lives within five miles of you = B. 8 of them until one says he or she lives within five miles of you. = C. 15 of them until one says he or she lives within five miles of you. =
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.
