Approximately 10.3% of American high school students drop out of school before graduation. Assume the variable is binomial. Choose 11 students entering high school at random. Find the probabilities. Round the answers to at least four decimal places. (a)All 11stay in school and graduate P(all 11 stay in school and graduate)= (b)No more than 4 drop out P(no more than 4 drop out)= (c)At least 6 graduate P(at least 6 graduate)=
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.
