The number of requests for assistance are received by a towing ser-vice at an average steady rate of 4 per hour. If, during a normal day therequests are received independently of one another, compute the probabilitythat exactly ten requests are received during a particular 2-hour period of anormal day. Suppose, that the dispatcher ignored at least one call between 2:25pm and 2:45pm. What is the probability that no more than one call was received during this time period? What is the probability that no more thanone call is received between 2:45 pm and 3:00pm?

A company prices its tornado insurance using the following assumptions: • In any calendar year, there can be at most one tornado. • In any calendar year, the probability of a tornado is 0.11. • The number of tornadoes in any calendar year is independent of the number of tornados in any other calendar year. Using the company's assumptions, calculate the probability that there are fewer than 4 tornadoes in a 11-year period.
