BMW company has collected the statistics about 3600 BMW cars (each with a certain problem) after 10 years of usage. The problem of each car occurred because the proper maintenance has been neglected. Some cars have accidents (A), and the rest did not. There are basically three problems: Motor (M), Structural (S) and Electrical (E) that occur with probabilities of 0.3, 0.2 and 0.5 respectively. The probability of an accident because of a motor problem is 0.2, because of a structural problem is 0.5 and because of an electrical problem is 0.4. Answer the following: a) What is the main feature of the three events, M, E and S? Are they independent? b) For a car with a motor problem, what is the probabiliy that it has an accident? c) For a car with an electrical problem, what is the probabiliy that it did not have an accident? d) How many cars will likely to have an accident and motor problem? e) How many cars are likely to have an accident?
