FarmMilks Sdn. Bhd produce dairy products. 70% of the dairy products sold are banana flavor milk and 30% are kurma flavor milk. The type of dairy product purchased by each of the next 20 customers will be recorded. Given a random variable x as number of dairy product purchased among these 20 customers, answer the following questions: a) Determine whether x is a binomial random variable or geometry random variable. b) Calculate the probability that exactly eight dairy product purchased are banana flavor milk. c) Calculate the probability that between seven and ten (inclusive) are banana flavor milk. d) Calculate the probability that between three and five (inclusive) are kurma flavor milk.
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.
