multiplication rule Medical test example. A medical test has been developed to test for a certain condition. The outcomes of this test are not perfect, but reasonably accurate. The probability of a positive or negative result depends on whether the individual actually has the condition or not, and will be given as a conditional probability. p( + | condition ) = 0.95 p( - | condition ) = 0.05 p( - | not condition) = .90 p( +| not condition) = 0.10 Find the probability of each of the four possible outcomes if 20% of those tested have this condition
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.

Medical test example.
A medical test has been developed to test for a certain condition.
The outcomes of this test are not perfect, but reasonably accurate.
The
p( + | condition ) = 0.95
p( - | condition ) = 0.05
p( - | not condition) = .90
p( +| not condition) = 0.10
Find the probability of each of the four possible outcomes if 20% of those tested have this condition.
