A physical therapist at Enormous State University knows that the football team will play 40 percent of its games on artificial turf on this season. He also knows that a football player’s chance of incurring a knee injury are 50 percent higher if he is playing on artificial turf instead of grass. If a player’s probability of knee injury on artificial turf is 0.42, what is the probability that (a) A randomly selected football player incurs a knee injury? (b) A randomly selected football player with a knee injury incurred the injury playing on grass?
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.
