An office worker receives an average of 22.5 email messages per day. If his working day lasts seven and a half hours, what is the probability that: (a) he receives no emails in an hour? (b) he receives one email in an hour? (c) he receives two or fewer emails in an hour? (d) he receives more than four emails in an hour?
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.
An office worker receives an average of 22.5 email messages per day. If his working day lasts seven and a half hours, what is the probability that: (a) he receives no emails in an hour? (b) he receives one email in an hour? (c) he receives two or fewer emails in an hour? (d) he receives more than four emails in an hour?
