5. At a subway station, the waiting time in minutes for a new train to arrive follows an exponential 1 distribution with parameter x = 4 (a) You know the last train left at 9:00 AM. What is the probability the next train comes after 9:10 AM? (b) What is the expected waiting time between trains coming the subway station? (c) You have already waited 5 minutes for a train, what is the probability that you will have to wait more than 20 minutes in total for the next train to come to the station? (d) Suppose you are at a very busy station. You need to wait for three (3) trains to come through the station to move to the top of the queue and get a seat. As you enter the station, you add yourself to the end of the queue. How long do you expect to wait to get a seat in the train? Assume that the waiting times between each train is independent and identically distributed.
What is the probability that the total of two randomly chosen numbers exceeds 3, where the first number is chosen from a uniform distribution between 0 and 2, and the second number is selected from an exponential distribution with a mean of 1?

The following are the probability distributions for the cost of textbooks in the fall semester for two different majors. Each probability represents the chance that the total cost of a student's books will be the given amount. Calculate the absolute difference in the expected cost of textbooks for the fall semester for these two majors. Express your answer rounded to two decimal places.

The useful life of Johnson rods for use in a particular vehicle follows an exponential distribution with an average useful life of 5.2 years.You have a three-year warranty on your vehicle’s Johnson rod. What is the probability that the Johnson rod doesn’t fail before then? That is, what is the probability that its useful life doesn’t end before three years?b.If the vehicle manufacturer wants to limit the number of claims on the three-year warranty to 20%, what should the average useful life of the Johnson rod be?

In finance, one example of a derivative is a financial asset whose value is determined (derived) from a bundle of various assets, such as mortgages. Suppose a randomly selected mortgage in a certain bundle has a probability of 0.06 of default. (a) What is the probability that a randomly selected mortgage will not default? (b) What is the probability that four randomly selected mortgages will not default assuming the likelihood any one mortgage being paid off is independent of the others? Note: A derivative might be an investment that only pays when all four mortgages do not default. (c) What is the probability that the derivative from part (b) becomes worthless? That is, at least one of the mortgages defaults. (a) The probability is (Type an integer or a decimal. Do not round.)
At the store 10 cashiers are busy with customers, and you are the next one in the line. Suppose the times cashiers spent on customers are independently and identically distributed following an exponential distribution with a mean of 2 minutes, (a) What is the probability density function of your wait time? (b) If there is only 1 cashier and 36 people in front of you, what is the probability, approximately, that you need to wait more than 144 minutes? Assume the times spent on each customer are independently distributed following an exponential distribution with a mean of 3 minutes. (Hint for (b): CLT).
