A teacher has ordered four laptops for his students. Those laptops were dropped during the shipment process to the school and and classified as containing either, a no, a minor or, a major defect. Previously, 20% of the dropped laptops had no defect, 30% had a minor defect and 50% had major defect. (Hint: The defect on the laptop occur independently). (e) What is the expected number of laptops with a minor defect, and the expected number of laptops with a major defect? (f) The conditional probability that two laptops have major defects given that two laptops have minor defects (g) The conditional probability that three laptops have major defects given that two laptop have minor defects? (h) The conditional probability distribution of the number o
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.
