operator working in an intercity telephone exchange receives an average of 5 conversation requests per minute. As it is known that the number of speeches received by the operator conform to the Poisson distribution, in one minute; a) What is the probability of getting 3 speech requests? b) What is the probability of more than 3 speech requests?
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.
