Suppоse thаt оnly 0.10% оf аll computers of а certain type, experience CPU failure during the warranty period. Consider a sample of 15,000 computers. a. What is the expected value (average) number of computers in the sample that have the defect? (3 points) b. Assuming Poisson distribution, what is the probability that more than 2 computers have the defect? (3 points) c. Assuming Poisson distribution, what is the probability that no sampled computers have the defect? (4 points)
