An automobile dealer sells two brands of new cars. One, C, is primarily American in original; the other, G, is primarily Japanese. The dealer performs repair work under warranty for both brands. Each warranty job is classified according to the primary problem to be fixed. If there is more is more than one problem in a given job, all problems are listed separately. Records for the past year indicate the following numbers of problems.
(see the attached file for data)
a. What is the probability that a randomly chosen problem comes from brand C?
b. Serious problems are hose involving the engine or transmission. What is the probability that a randomly chosen problem is serious?
c. The dealer is fully reimbursed for all brand C problems and all brand G engine, transmission, and fit/finish problems. What is the probability that a randomly chosen problem is not fully reimbursed?
To compute probability we use the classical definition P(A) = No. of favourable cases/Total ...
This solution helps with questions about probability.
