Suppose that at a particular bus stop, Brown buses arrive according to a Poisson process with a constant rate of 3 per hour. The travel time on the Brown bus to your class is 7 minutes. (The Brown bus drops you off at your class.).  When you approach the bus stop, you see that you have just missed a Blue bus. Class starts in 20 minutes and it is exam day so you want to get to class as soon as...

Buses arrive at a certain stop according to a Poisson process with rate λ. If you take the bus from that stop then it takes a time R, measured from the time at which you enter the bus, to arrive home. If you walk from the bus stop then it takes a time W to arrive home. Suppose your policy when arriving at the bus stop is to wait up to time s, and if a bus has not yet...

Alice takes the bus to school. The bus is scheduled to arrive at a bus stop at 9:30am. In reality, the time the bus arrives is uniformly distributed between 9:28am and 9:40am. Let ? be the number of minutes it takes, starting from 9:28 am, for the bus to arrive to the bus stop. Then ? is uniformly distributed between 0 and 12 minutes. (a) If Alice arrives at the bus stop at exactly 9:33 am, what is the probability...

Problem 3. Alice is waiting for a bus at a bus stop. She needs to take a bus number 10 or 12, and she takes the first suitable bus that arrives. The arrival time of bus 10 is exponential with λ10 = 6/19, and the arrival time of bust 12 is exponential with λ12 = 3/19. Moreover, arrival times of 10 and 12 are independent. What is the probability that Alice will take bus number 10 instead of bus number...
