A certain snack vending machine dispenses the incorrect item, on average, 4.2 times every day. Assume that the number of incorrect items dispensed on any given day, X, is a Poisson random variable. What is the probability that the machine will dispense exactly 9 incorrect items tomorrow? ANSWER: (Use only the appropriate formula and/or statistical table in your textbook to answer this question.

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.
