Thirty percent of an airline’s planes are jumbo jets. Sixty percent of the airline’s pilots are 45 years or older. If pilots are assigned to planes independently of age, what is probability that a randomly selected plane is a jumbo jet being flown by a pilot under 45 years of age?
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.
