Suppose on average, a judge reviews 6 cases per day. Further, suppose the number of cases a judge reviews per day follows a Poisson distribution. What is the variance of the number of cases a judge reviews in a day? Round to the third decimal point.

Suppose a judge is scheduled to hear 6 cases today. Each case has a 75% chance of resulting in a guilty verdict. What is the probability (as a decimal) that all 6 cases turn out guilty? Round to the second decimal place.
The university police department must write, on average, five tickets per day to keep department revenues at budgeted levels. Suppose the number of tickets written per day follows a Poisson distribution with a mean of 6 tickets per day. Find the probability that exactly 7 tickets are written on a randomly selected day from this distribution.
Suppose that the number of snake bites cases seen at Dammam Hospital in a year has a Poisson distribution with average 6 bite cases ? The probability that the number of cases will be less than 2 in 6 months 0.1992 0.138 0.1494 0.0498

6. A certain typing agency employs 3 typists. The average number of errors per article is 2.2 when typed by the first typist, 2.7 when typed by the second, and 3.1 when typed by the third. If your article is equally likely to be typed by any of the three typists, approximate the probability that it will have no errors. Again assume that for each typist the number of errors follows a Poisson distribution.
Suppose the number of spam calls a person receives per day can be assumed to follow a Poisson distribution with parameter λ=2. What is the probability that Jacob will receive at least two spam calls in a day? Show your steps in calculating your answer
Assume that the number of pieces of junk mail per day that a person receives in their mail box follows the poisson distribution and averages 4.3 pieces per day. what is the probability that this person will receive more than two pieces of junk mail tomorrow?
A civil engineer has been studying the frequency of vehicle accidents on a certain stretch of interstate highway. Longterm history indicates that there has been an average of 1.70 accidents per day on this section of the interstate. Let r be a random variable that represents number of accidents per day. Let O represent the number of observed accidents per day based on local highway patrol reports. A random sample of 90 days gave the following information. r 0 1...
Huang’s television-repair service receives an average of 9 TV sets per 6-hour day to be repaired. The service manager would like to be able to tell customers that they can expect their TV back in 4 days. What average repair time per set will the repair shop have to achieve to provide 4-day service on the average? (Assume that the arrival rate is Poisson distributed and repair times are exponentially distributed.) (Round answer to 2 decimal places, e.g. 2.75.) Average...
Suppose that on average, there are 1.2 defects per 75 square foot roll of wallpaper and the number of defects follows a Poisson distribution. Determine the probability that a 25 square foot roll of wallpaper will have one or fewer defects?
