40% of the people staying in a hotel business have breakfast at the hotel. 30 of them have dinner at the hotel. 20 of them eat breakfast and dinner at the hotel. The hotel would like to choose a random tourist from among the guests and reward them by paying all their expenses. Since it is known that the person to be rewarded is a tourist who has breakfast at the hotel, what is the probability of being a tourist who also eats dinner at the hotel?
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.
