Winston, a dog, loves to play fetch. He catches each ball mid-air independently with probability 0.4 (i.e. Bernoulli random variable with p = 0.4). (a) What is the probability that in four tosses, Winston makes exactly two mid-air catches? Round your answer to two decimal places. (b) On average, how many mid-air catches do you expect Winston to make (out of four tosses)? Round your answer to one decimal place.
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.
