Please solve both parts: 1. The number of parking tickets issued in a certain tity on any given weekday has a Poisson distribution with parameter - 20. (Round your answers to four decimal places.) (a) calculate the approximate probability that between 35 and 70 tickets are given out on a particular day. (b) Caloulate the approximate probability that the total number of tickets given out during a 5-day week is between 225 and 285. (c) Use software to obtain the axact probabilities in (a) and (b) and compara to their approximations. Caloulate the AXact prohability that between 35 and 70 tickets are glven ut on a particular day. Caloulate the AXact probability that the total number of tickkets given out during a 5-day WeRk is between 225 and 285.
