A company that produces fine crystal knows from experience that 10% of its goblets have cosmetic flaws and must be classified as "seconds." Among six randomly selected goblets, how likely is it that only one is a second? Among six randomly selected goblets, what is the probability that atleast two are seconds? If goblets are examined one by one, what is the probability that at most five must be selected to find four that are not seconds?
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.
