Your car is making a funny noise. You believe that the problem is either with the wheel or the axle, and you believe the probability is 0.3 that the wheel needs to be replaced, and 0.7 that the axle needs to be replaced. You need to decide whether to replace the wheel or the axle first. The cost of each ilternative is given in the following table (if you decided to replace the wrong part first, you have to eplace both of them). The Axle is broken _p = 0.7 1500 900 The Wheel is broken p = 0.3 600 Replace Wheel First Replace Axle First 1500 a) Find the EV of each decision alternative. Which part should you replace first? b) What is the EVPI?

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.
