A telephone company’s goal is to have no more than five monthly line failures on any 100 kms of line. The company currently experiences an average of two monthly line failures per 50 kms of line. Let x denote the number of monthly line failures per 100 kms of line. Assuming x follows a Poisson distribution: Find the probability that the company will: a) meet its goal on a particular 100 kms of line, b) not meet its goal on a particular 100 kms of line, c) have no more than five monthly failures on a particular 200 kms of line, d) have more than 12 monthly failures on a particular 150 kms of line
