The annual number of industrial accidents occurring in a particular manufacturing plant is known to follow a Poisson distribution with mean 12. What is the probability of observing exactly 12 accidents during the coming year? What is the probability of observing no more than 12 accidents during the coming year? What is the probability of observing at least 15 accidents during the coming year?
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.
