A travelling salesman makes a sales on 65% of his calls on regular customers.he makes four calls each day. A. Construct the probability distribution of X, the number of sales made each day. B. Find the probability that, on a randomly selected day, the salesman will make a sale. C. Assuming that the salesman makes 20 sales calls per week, find the mean and standard deviation of the number of sales made in per week.
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.
