The following table represents the joint probability distribution of the number of phone calls received per hour by operator A and operator B at a call center. a. Determine the probability of A receiving 1 call and B receiving 2 calls. b. What is the probability that at least five calls were received in total by both operators? c. If during a particular hour B received at most two phone calls, what is the probability that A received four phone calls?
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.
The following table represents the joint
a. Determine the probability of A receiving 1 call and B receiving 2 calls.
b. What is the probability that at least five calls were received in total by both operators?
c. If during a particular hour B received at most two phone calls, what is the probability that A received four phone calls?
