A person passing through an intersection will find someone running the red light with probability 0.4. What is the probability that in her next 5 passing through the intersection, she will see no one running the red light? what is the probability that in at least one of her 5 visits, she will find someone running the red light? What are the mean and standard deviation of the variable 'number of passing when red light was run'?
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.
