A business manager who needs to make many phone calls has estimated that when she calls a client, the probability that she will reach the client right away is 50%. If she does not reach the client on the first call, the probability that she will reach the client on her second call in the next hour is 20%. And if she does not reach the client on either the first or second call, the probability that the will reach the client on her third call in the hours after that is 10%. What is the probability that the manager will reach her client in three or fewer calls? What probability distribution did you use to solve this?
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.
