An internal study by the Technology Services department at Lahey Electronics revealed company employees receive an average of 4.6 non-work-related e-mails per hour. Assume the arrival of these e-mails is approximated by the Poisson distribution a. What is the probability Linda Lahey, company president, received exactly 1 non-work-related e-mail between 4 p.m. and 5 p.m. yesterday? (Round your probability to 4 decimal places.) Probability b. What is the probabllity she received 8 or more non-work-related e-mails during the same period? (Round your probability to 4 decimal places.) Probability c. What is the probability she received four or less non-work-related e-mails during the period? (Round your probability to 4 decimal places.) Probability
