One-half percent of the population has COVID-19. There is a test to detect COVID-19. A positive test result is supposed to mean that you have COVID-19 but the test is not perfect. For people with COVID-19, the test misses the diagnosis 2% of the times. And for the people without COVID-19, the test incorrectly tells 3% of them that they have COVID-19. What is the probability that a person picked at random will test positive? Select one: O a 00164 O ba.056 O c. 0.035 O d. 0.0061

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.
