At 12:00 noon a stand begins selling hamburgers and hot dogs. Each customer will order either a hamburger or hot dog, Assume 78% of customers choose hot dog and 22% choose hamburger. Also assume all orders are independent. The rule is that immediately after hot dog number 13 is ordered and sold, the stand will close and stop taking any future orders. What is the probability that, upon closing, the stand has sold exactly 3 hamburgers? (Note this implies that exactly 16 total orders are sold.) Give answer as a decimal between 0 and 1, accurate to at least 4 decimal places.
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.
