It is estimated that 30 percent of all adults in the United States are obese and that 3 percent suffer from diabetes. If 2 percent of the population both is obese and suffers from diabetes, what percentage of the population either is obese or suffers from diabetes
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.
Binomial Distribution
Binomial is an algebraic expression of the sum or the difference of two terms. Before knowing about binomial distribution, we must know about the binomial theorem.
Q3. It is estimated that 30 percent of all adults in the United States are obese and that 3 percent suffer
from diabetes. If 2 percent of the population both is obese and suffers from diabetes, what
percentage of the population either is obese or suffers from diabetes? 14. Welds of tubular joints
can have two types of defects, which we call A and B. Each weld produced has defect A with
the proportion of welds that has (a) Either defect A or defect B (b) Neither defect.
