An accountant of an international company is working on a profit-and-loss report for the current fiscal year. The accountant reports that the company incurred a loss in 4 months out of the 12 months in the fiscal year. Let X be the number of months the company is suffering a loss in the next fiscal year. Discuss the adequacy of the model that X follows a binomial distribution with n=12 and p = 4/12. 6. On average, you receive 3 junk e-mails every 6 hours. Assume that the number of pieces of junk mail you receive each day follows the Poisson distribution. a. What is the expected number of junk e-mails in one day? What is the probability of receiving exactly two junk e-mails in a six-hours interval? b. An accountant of an international company is working on a profit-and-loss report for the current fiscal year.
