a hotel rents cars for its guest from four rental agencies. It is known that 20% are from agency X, 35% are from agency Y,15% are from agency Z and 30% are from agency K. If 10% of the cars from agency X, 6% from agency Y, 15% from agency Z and 8% from agency K need tune-ups. What is the probability that a car needing a tune-up come from agency Y? a)P(Y|T)? b)P(T)?
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.
