This problem involves the flipping of a fair coin. Assume that the coin is flipped 4 times, and the random variable X is defined to be 3 times the number of heads minus 5 times the number of tails. How many different values are possible for the random variable X?
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.
