The proportions of families with various numbers of children age 18 or under in a small town are given in the following table. One family is randomly selected from this town. x 0 1 2 3 4 5 P(X) 0.1 0.4 0.30.1 0.05 0.05 Find the probability that the selected family has at least 3 children age 18 or under.
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.
