Evie was doing an experiment for her biology class. She determined that if she randomly selected a student from the class, the probability that they had brown hair was 0.5, the probability that they had blue eyes was 0.57, and the probability that they had neither brown hair nor blue eyes was 0.2. Determine the probability that a randomly selected student has brown hair and blue eyes.

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.
