The mean number of breakdowns of a conveyor belt per month at a local factory is 56. Assume that each breakdown occurs randomly and independently. Let X = the number of of breakdowns of a conveyor belt per month. (a) Is X a discrete or continuous random variable? (Type: Discrete or Continuous) (b) What is the exact probability that anywhere from 55 to 57 breakdowns will occur in the next month? Answer: (c) Use the normal approximaion to the poisson distribution to estimate the probability in part (b). Answer:
