Solve the given problem with solutions and write the conclusion. The probabilities that a street food vendor could sell 10, 20, 30, 40, and 50 number of servings of kwek-kwek in a day are 0.10, 0.35, 0.30, 0.20, and 0.05 respectively as shown on the table below. Find the mean, variance, and standard deviation of the probability distribution of 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.
