On average, Nancy has noticed that 18 trucks pass by her apartment daily (24 hours). In order to find the probability that more than 5 trucks will pass her apartment in a 6-hour time period using the Poisson distribution, find the average number of trucks per 6 hours. Round your answer to three decimal places, if necessary.

For each probability and percentile problem, draw the picture.Suppose that the length of long distance phone calls, measured in minutes, is known to have an exponential distribution with the average length of a call equal to 12 minutes. Part (g) Find the probability that a phone call lasts less than 13 minutes. (Round your answer to four decimal places.) Part (h) Find the probability that a phone call lasts more than 13 minutes. (Round your answer to four decimal places.) Part (i) Find the probability that a phone call lasts between 9 and 13 minutes. (Round your answer to four decimal places.)

A vaccine has a 87% probability of being effective in preventing disease. The probability of getting the disease if a person is not vaccinated is 46%. In a certain geographic region, 21% of the people get vaccinated. If a person is selected at random, find the probability that he or she will contract the disease. Round your answer to three decimal places. Also, draw a tree diagram or a table to support your work.

The random variable x represents the number of emails a student receives on a day. Assume it has a Poisson distribution with a mean of 14.3 emails. Find the probability that in a random day the student receives 3 emails. Round your answer to four decimal places.
