Breast cancer occurs in 2% of all American women. Mammograms used to detect breast cancer typically test positive 80% of the time for women that actually have breast cancer and test negative 85% of the time for women that actually don't have breast cancer. If a woman tests positive, what is the probability that she has breast cancer.
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.
