Advertisements state that LED light bulbs should last much longer than traditional light bulbs. Suppose there is an 85% that an LEDlightbulb lasts ten years. Using this kind of lightbulb, ahomeowner replaced the 3 lightbulbs in the bathroom light fixture. c.What is the probability that all threeof them last ten years? d.What is the probability that at least oneof the three lightbulbslasts ten years?
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.
