If the airline sells 644 tickets on the night flights, how many unsold tickets can the airline expect on the morning flights?
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.
an airline offers the same number of tickets for the morning and night flights. When the airline analyzed ticket sales, they determined that the ratio for the number of sold tickets to the number of unsold tickets was 3:5 on the morning flights and 7:1 on the night flights. If the airline sells 644 tickets on the night flights, how many unsold tickets can the airline expect on the morning flights?
