n each part, tell whether the sampling method is random and also if it is biased. If it is not random, explain why. And if is biased explain how.

A contingency table is indeed a type of frequency distribution table that displays two variables at the same time.

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.
