Question 12<>Complaints about an Internet brokerage firm occur at a rate of 1.4 per day. The number of complaintsappears to be Poisson distributed. Find the probability that the firm receives more than 4 complaints in a3-day period.Round all final answers to 1 decimal place and express answers in percent form (i.e. 30.0% instead of0.3)(a) What is the probability of receiving less than or equal to 4 complaints in a 3-day period?(b) What is the probability of receiving more than 4 complaints in a 3-day period?

Let the random variable X be defined as the number of complaints received by the firm in a 3-day…
