(A) What is the probability that exactly 8 of them weigh more than 20 pounds? (B) What is the probability that more than 6 weigh more than 20 pounds? (C) What is the probability that fewer than 6 weigh more than 20 pounds?
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.
