Consider a very small barangay consisting of 6 qualified voters. Let us label them A, B, C, D, E, and F. There are two candidates vying for the position namely, Digong and Mar. What we do not know is that Voters A, B, C, and D already decided to vote for Digong while voters E and F will elect Mar. We only have the resources of getting a sample size of 3. Let X be a random variable giving the number of voters who will elect Digong among the sample size of 3. a. What is the random variable size of 3. b. Construct the probability mass function of X where X is the number of voters who will elect Digong. c. Find the average number of voters that will elect Digong. d. Compute the variance and the standard deviation of the probability distribution.
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.
