A local high school has both male and female students. Each student either plays a sport or doesn't. The two-way table summarizes a random sample of 70 students. Female Male No sport 10 7 Sport 32 21 Let no sport be the event that a randomly chosen student (from the table) does not play a sport. Let male be the event that a randomly chosen student (from the table) is male. Find the following probabilities. Write your answers as decimals. (a) P(male) = (b) P(no sport and male =) (c) P(no sport | male = )
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.
