A biostatistician analyzes a group of pregnant women. Of these, 90% have normal fetuses, but 10% have genetic abnormalities in their fetuses. Of those with normal fetuses, 3% were over 35. Of those with genetic abnormalities in their fetuses, 20% were over 35. What is the probability of a normal fetus given a the patient is over 35?
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.
