A library subscribes to two different weekly news magazines, each of which is supposed to arrive in Wednesday's mail. In actuality, each one could arrive on Wednesday (W), Thursday (T), Friday (F), or Saturday (S). Suppose that the two magazines arrive independently of one another and that for each magazine P(One of the two magazines arrives on W)=0.4 P(One of the two magazines arrives on F)=0.2 P(One of the two magazines arrives on T)=0.3 P(One of the two magazines arrives on S)=0.1 Let X denote the total number of days beyond Wednesday that it takes for both magazines to arrive. What are the possible values of X? Select one: 0,1,2,3,4,5 0,1,2,3 1,2,3,4 0,1,2,3,4 1,2,3,4,5 1,2,3 0,1,2,3,4,5,6 1,2,3,4,5,6 None
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.
