Ten percent of the engines manufactured on an assembly line are defective. If engines are randomly selected one at a time and tested, (a) what is the probability that the first non-defective engine will be found on the second trial? (b) what is the probability that the third non-defective engine will be found on the fifth trial? on or before the fifth trial?
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.
