The number of hits to a web site follows a poisson process. hits occur at the rate of 0.8 per minute between 7: 00 p. m. and 9: 00 p. m. given below are three scenarios for the number of hits to the web site. compute the probability of each scenario between 7 : 28 p. m. and 7: 32 p. m. and interpret the results. (a) exactly four hits (b) fewer than four hits (c) at least four hits
