Suppose that a call to a radio station, Sinaree FM, get connected with a probability of 0.05. Assume calls are independent. a. What is the probability that the 6-th call made is the second call that gets connected? b. What is the probability that more than four calls have to be made before getting connected?
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.
