An airline company has an airbus a330-200 fleet, each of which can carry 250 passengers. The company has the experience that some ticketed travellers do not show up. Relying on that observation, the company sells (250+4) seats. The probability that a traveller will not show up is 3,1 %. Calculate the probability (in %) that more than 250 travellers will show up, causing a shortage of seats. Correct Answer: 4,38
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.
