The arrival times of workers at a factory first-aid room satisfy a Poisson process with an average of 2 per hour. (i) What is the probability that there is at least 1 hour between two arrivals at the first-aid room? (ii) What is the probability that at least 3 workers visit the first-aid room during a 2-hour period
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.
