Consider a food stall offering “Biryani” and “Pulao” at a distant place in Karachi. Since people in Karachi seem to like biryani more than puloa, the probability that a customer would order biryani is 0.8. [15] a. Find out the probability that the stall owner would sell more than 5 biryanis to the next 12 customers. b. What is the probability that 4th customer would be the first one ordering biryani that day c. What is the expected sale of biryani among the next 50 customers?
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.
