Question

The number of hits to a Web site follows a Poisson process. Hits occur at the rate of 1.8 per minute between 7:00 P.M. and 12:00 P.M. Given that x hits to the Web site between 9: 46 P.M. and 9:51 P.M 25. Compute the probability of x is fewer than seven. 26. Compute the probability of x is more than seven For the past 108 years, a certain state suffered 23 direct hits from major (category 3 to 5) hurricanes. Assume that this was typical and the number of hits per year follows a 27. What is the probability that the state will not be hit by any major hurricanes in a single 28. What is the probability that the state will be hit by at least three major hurricanes in a A private parking facility has 6 parking lots. The probabilities of number of cars (x) parking in Poisson distribution year? single year, as happened several years ago? those lots are as the following table: 0 2 4 Double-click to hide white space 0.15 0.2 0.25 0.05 0.05 29. Find the probability of at least 4 cars are parking 30. Find the probability of in between 2 and 5 lots are empty
