A disease affects 1 out of every 500 people. If you have the disease, you test positive 90% of the time. If you don’t have the disease, you test negative 99% of the time. If you test positive, what is the probability that you have the disease?
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.
A disease affects 1 out of every 500 people. If you have the disease, you test positive 90% of the time. If you don’t have the disease, you test negative 99% of the time.
If you test positive, what is the probability that you have the disease?
