9. Suppose that a company's production of car engines may be treated as a normal random variable with a mean of 15,000 and a standard deviation of 2,000. What is the probability that the company produces on a day between 10,000 and 20,000 car engines? (a) 0.7887 (b) 0.9938 (c) 0.9876 (d) 0.9924 10. The number of particles X emitted by a radioactive source follows a Poisson distri- bution with A = 7 every second. Find the probability that less than 8 particles are emitted in 2 seconds (a) 0.7291 (b) 0.0621 (c) 0.0316 (d) 0.5987
