State the probability distribution (with its parameter and parameter value) that describes the number of calls received. (b) Calculate the probability that there will be 2 calls in one minute. (c) Calculate the probability that there will be 5 calls in a 15 minute period.
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.
During normal working hours, a call centre receives an average of 60 calls per hour.
(a) State the
(b) Calculate the probability that there will be 2 calls in one minute.
(c) Calculate the probability that there will be 5 calls in a 15 minute period.
