(a) Compute the probability that exactly five students are left-handed. (b) Compute the probability that at most four students are left-handed. (c) Compute the probability that at least six students are left-handed.
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.
Suppose that you are in a class of 28 students and it is assumed that approximately 9% of the population is left-handed. (Give your answers correct to three decimal places.)
(b) Compute the probability that at most four students are left-handed.
(c) Compute the probability that at least six students are left-handed.
