An insurance company has a toll-free phone number available from 10 a.m. to 6 p.m. every day, for customers to get a quote for car-insurance. Past history indicates that an average of 0.2 calls are made to the toll-free number per minute. The count X of number of calls made to the toll-free number can be modelled by a Poisson distribution. Using the Poisson probability formula, calculate the probability of getting at least two calls in a randomly selected minute. (Correct to three decimal places)
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.
