The average service time given to a student by the staff working in the library is 15 minutes. Students come to the library every 20 minutes and their arrivals are Poisson distributed. a) Find the probability of having 5 or more students in the queuing system. b) Calculate the average number of students waiting in the queue. c) Calculate the average time students spend on the service.
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.
