Find the probability that if Air-USA books 23 persons, not enough seats will be available. prob = Is this probability low enough so that overbooking is not a real concern for passengers if you define unusual as 5% or less? O yes, it is low enough not to be a concern O no, it is not low enough to not be a concern What about defining unusual as 10% or less? O yes, it is low enough not to be a concern O no, it is not low enough to not be a concern
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.
Given :
Air-USA has a policy of booking as many as 23 persons on an airplane that can seat only 21.
Studies have revealed that only 83% of the booked passengers actually arrive for the flight.
Therefore, the probability of a person arrive is 0.83
Let X denotes number of passengers arriving
It will follow a Binomial distribution
