There are 4 black balls, and 4 white ones in an urn. You pick 4 balls. a. Let X be the number of black balls you get. What are the values of X and the probabilities associated with each value? b. Suppose you win PhP500 per black ball you get, and an extra PhP2000 if you get all 4 black balls. What is your expected gain?
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.
