Suppose that 15% of milk boxes contain a prize and the other 85% contain the message, “Sorry, try again.” Consider the random variable x, where x = number of boxes purchased until a prize is found. What is the probability that at most two boxes are purchased until a prize is found? What is the probability that exactly four boxes are purchased until a prize is found? What is the probability that more than four boxes are purchased until a prize is found?
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 15% of milk boxes contain a prize and the other 85% contain the message, “Sorry, try again.” Consider the random variable x, where x = number of boxes purchased until a prize is found.
