Phone calls arrive at the rate of 48 per hour at the reservation desk for Regional Airways.a. Compute the probability of receiving three calls in a 5-minute interval of time.b. Compute the probability of receiving exactly 10 calls in 15 minutes.c. Suppose no calls are currently on hold. If the agent takes 5 minutes to complete thecurrent call, how many callers do you expect to be waiting by that time? what is theprobability that none will be waiting?d. If no calls are currently being processed, what is the probability that the agent can take3 minutes for personal time without being interrupted by a call?
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.
Phone calls arrive at the rate of 48 per hour at the reservation desk for Regional Airways.
a. Compute the probability of receiving three calls in a 5-minute interval of time.
b. Compute the probability of receiving exactly 10 calls in 15 minutes.
c. Suppose no calls are currently on hold. If the agent takes 5 minutes to complete the
current call, how many callers do you expect to be waiting by that time? what is the
probability that none will be waiting?
d. If no calls are currently being processed, what is the probability that the agent can take
3 minutes for personal time without being interrupted by a call?
