[Bayes' Theorem, Discrete Random Variables] It is known that 90% of new cars produced by a certain company have on average λ malfunctions per 1 km of covered distance. Besides this, it is known that remaining 10% of new cars were produced with a defect which increases the average malfunction rate to 21. The two types of cars are indistinguishable otherwise. When (a) Suppose that only a single malfunction has occured with a randomly selected car over 1,000 km of distance. What is the probability that the car is from the defective group, and how does it depend on X? (b) For a randomly selected car, find a minimum distance covered with no malfunctions for the probability that the car is from the non-defective group is 95% or above (express the result as a function of X).
