Airport security personnel screen carry-on luggage foritems that are not allowed on planes. Most bags passthrough without a problem, but occasionally one is pulledaside for further inspection. Those inspections actuallyfind some item that must removed in 2 of every 5 bagsthat are pulled aside. If 7 of the people on a certain flighthad luggage that was subjected to further inspection,what’s the probability that at least 2 of them had itemsremoved?A) 0.159 B) 0.261 C) 0.420D) 0.580 E) 0.841
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.
