1) INTERNET TRAFFIC Data Set 27 "Internet Traffic" includes 9000 arrivals of Internet traffic at the Digital Equipment Corporation, and those 9000 arrivals occurred over a period of 19,130 thousandths of a minute. Let the random variable x represent the number of such Internet traffic arrivals in one thousandth of a minute. It appears that these Internet arrivals have a Poisson distribution. If we want to use Formula 5-9 to find the probability of exactly 2 arrivals in one thousandth of a minute, what are the values of , x, and e that would be used in that formula?

3) INTERNET TRAFFIC For the distribution described in Exercise 1, find the probability of exactly 2 arrivals in one thousandth of a minute.

I need help with the 3), please. Thank you very much.
