hire company has two lawnmowers which it hires out by the day. The number of demands per day may be modelled by a Poisson distribution with mean 1.5. In a period of 100 working days, how many times do you expect (i) neither lawnmower to be used (ii) some requests for a lawnmower to have to be refused?
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.
