In a random sample of 14 desks.a) Compute the probability that all of them have gum underneath.b) Compute the probability that 10 or less desks have gum.c) What is the probability that more than 10 have gum?d) What is the expected number of desks in the sample have gum?e) What is the SD of the number of desks with gum?
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.
