1. A major hotel chain keeps a record of the number of mishandled bags per 1,000 customers. In a recent year, the hotel chain had 5.50 mishandled bags per 1,000 customers. Assume that the number of mishandled bags has a Poisson distribution. What is the probability that in the next 1,000 customers, the hotel chain will have between 3 and 8 mishandled bags? (Keep four decimal places)
