Complaints about an Internet brokerage firm occur at a rate of 1.1 per day. The number of complaints appears to be Poisson distributed. Find the probability that the firm receives more than 4 complaints in a 3-day period. Round all final answers to 1 decimal place and express answers in percent form (i.e. 30.0% instead of 0.3) (a) What is the probability of receiving 0 complaints in a 3-day period? (b) What is the probability of receiving 1 complaint in a 3-day period? (c) What is the probability of receiving 2 complaints in a 3-day period? (d) What is the probability of receiving 3 complaints in a 3-day period? (e) What is the probability of receiving 4 complaints in a 3-day period? (f) What is the probability of receiving less than or equal to 4 complaints in a 3-day period? (g) What is the probability of receiving more than 4 complaints in a 3-day period?
