Eye colors of 45 eighth grade students are recorded. There are 24 boys and 21 girls in the class. 9 boys and 8 girls have brown eyes. 7 boys and 9 girls have blue eyes, 8 boys and 4 girls have green eyes. Construct a contingency table with this information What is the probability that a randomly selected student will have green eyes? What is the probability that a randomly selected student is a girl given that they have brown eyes? What is the probability that a randomly selected student will have blue eyes or green eyes? What is the probability that a randomly selected student will have blue eyes or a boy?
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.
