300 students in a high school freshman class are surveyed about what kinds of pets they have. Of the 300 students, 200 have a dog, 180 have a cat, and 150 have a cat and a dog. Using this information, answer each of the following questions. Let D be the event that a randomly selected student has a dog and C be the event that a randomly selected student has a cat. What is P(D), the probability that a student in the class has a dog? What is P(C), the probability that a student in the class has a cat? What is P(D and C), the probability that a student in the class has a dog and a cat?

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.
