An insurance company has a toll-free phone number available from 10 a.m. to 6 p.m. every day, for customers to get a quote for car-insurance. Past history indicates that an average of 0.2 calls are made to the toll-free number per minute. The count X of number of calls made to the toll-free number can be modelled by a Poisson distribution. Using the Poisson probability formula, calculate the probability of getting at least two calls in a randomly selected minute. (Correct to three decimal places)

A university is considering setting up an information desk manned by one employee. Based on information obtained from similar information desks, it is believed that people will arrive at the desk at the rate of 18 per hour. It takes an average of 2 minutes to answer a question. It is assumed that arrivals are Poisson and answer times are exponentially distributed. What is the arrival rate? (Include the units.) What is the service rate? (Include the units.)

Radio frequency identification (RFID) is an electronic scanning technology that can be used to identify items in a number of ways. One advantage of RFID is that it can eliminate the need to manually count inventory, which can help improve inventory management. The technology is not infallible, however, and sometimes errors occur when items are scanned. The probability that a scanning error occurs is 0.0069. 1. Find the probability that the number of items scanned incorrectly is between 16 and 20 , inclusive, from the next 5100 items scanned. *Kindly explain the procedure in Excel for this* A) The probability is (Round to four decimal places as needed.) 2. Find the expected number of items incorrectly from the next 5100 items B) The probability is (Round to four decimal places as needed.)

Tom the cat patrols the house in search of the mouse Jerry, who wants to get into the kitchen for something to eat. After leaving the kitchen, Tom will return after a random amount of time, which follows an exponential distribution with mean 20 seconds. Suppose Jerry needs 10 seconds to get across the house, and starts 5 second after Tom leaves the kitchen. What is the probability that Jerry the mouse will get caught?
