In the past 30 days, Roger Urban has sold either 8, 9, 10, or 11 computer units. It never sold less than 8 or more than 11. Assuming that the past level of transactions remains the same to the future, find the probabilities for the numbers of computer units sold if sales were 8 computers on 10 days, 9 computer units on 12 days, 10 computer units on 6 days and 11 computer units on 2 days. Required: Provide for the probability of the sales that may occur using the probability table.
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.
