Two students have started a business to seal driveways during the summer months. They rent a pickup truck and a power sprayer. With this they will use a tar-based spray to seal asphalt driveways. Past experience has shown that the best time to sign up customers is to ring their doorbells between 5:00 and 8:00 p.m. on any weekday evening. Any jobs that they obtain will be completed the next day. In the months of June, July and August they find that they get an average of 2 customers per hour ringing doorbells. a) What is the probability that they will get from 5 to 9 jobs in an evening of soliciting? The probability that they will get from 5 to 9 jobs in an evening of soliciting is? b) They charge $25 per driveway. If the truck costs $50 per day, and the spraying equipment costs $20 per day and the material to seal one driveway costs $5, what is the probability that they will make a profit on any given day? The probability that they will make a profit on any given day is?

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.
