1) The number of cracks in a section of interstate highway that are significant enough to require repair is assumed to follow a Poisson distribution with mean of three cracks every five miles. What is the probability that there are exactly two cracks that require repair in 3 miles of highway?
2) The volume of a shampoo filled into a container is a continuous random variable uniformly distributed with 240 and 260 milliliters. What is the probability that the container is filled with MORE THAN the advertised target of 255 milliliters?
3) The time between arrivals of taxis at a busy intersection is exponentially distributed with a mean of 10 minutes. What is the probability that you wait between 10 and 20 minutes for a taxi?

1). A group of students plans a tour. The charge per student is $66 if 25 students go on a trip. If more that 25 students participated, the charge per student is reduced by $2 times the number of students over 25. Find the number of students that will furnish the maximum revenue. The number of students that will furnish the maximum revenue is ______? The maximum revenue is $_______?
2) A motorboat is capable of traveling at a speed of 15 miles per hour in still water. On a particular day, it took 30 minutes longer to travel a distance of 18 miles upstream than it took to travel the same distance downstream. What was the rate of current in the stream on that day?

Larry offered to sell Stanley his car and told Stanley that the car had been driven only 25,000 miles and had never been in an accident. Stanley hired Cohen, a mechanic, to appraise the condition of the car, and Cohen said that the car probably had at least 50,000 miles on it and probably had been in an accident. In spite of this information, Stanley still thought the car would be a good buy for the price, so he purchased it. Later, when the car developed numerous mechanical problems, Stanley sought to rescind the contract on the basis of Larry's fraudulent misrepresentation of the auto's condition. Will Stanley be able to rescind his contract? Discuss.
