n an office, assume the number of arriving telephone calls has a Poisson distribution with an average rate of 10 calls per hour. (a) What is the probability that exactly 5 calls arrive in a given 40 minutes? (b) Assume the office opens at 9:00AM. What is the probability that the first call arrives between 9:05AM and 9:15AM?
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.
In an office, assume the number of arriving telephone calls has a Poisson distribution with an
average rate of 10 calls per hour.
(a) What is the probability that exactly 5 calls arrive in a given 40 minutes?
(b) Assume the office opens at 9:00AM. What is the probability that the first call arrives between 9:05AM and 9:15AM?
