From past experience, it was found out that in a certain factory, there is an average of two accidents per' month. Assuming a Poisson distribution, determine the probability that in a certain month selected at random there would be: no accident; exactly two accidents; less than four accidents.
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.
From past experience, it was found out that in a certain factory, there is an average of two accidents per' month. Assuming a Poisson distribution, determine the
no accident;
exactly two accidents;
