Two turtles are racing. Turtle A's time is exponentially distributed with a mean of two minutes. Turtle B's time is exponentially distributed with a mean of 3 minutes. Assume that their times are independent.
A. What is the the variance of the winner?
B.What is the pdf of the time difference between the loser and the winner (by how much faster does the turtle win?)

A call center has a mean waiting time of five minutes and is distributed exponentially. Find the probability that a call has to wait between three and six minutes.
8. On Halloween, the waiting time between trick-or-treaters, T (in minutes) is exponentially distributed with PDF fr(t) = te-t/5 for t > 0. Given that you have just waited 4 minutes since the last request for treats, your expected wait until the next request in minutes) is:
The time between arrivals of taxis is exponentially distributed with a mean of 10 minutes. a) You are fourth in line looking for a taxi. What is the probability that exactly 3 taxis arrive within one hour? b) Suppose the other three parties just decided to take the subway and you are now the first in line for the next taxi. Determine the time t such that the probability you wait less than t minutes from now until the next...
The time between calls to a plumbing supply business is exponentially distributed with a mean time between calls of 5-minutes. A) What is the probability that at least one call arrives within a 10-minute interval? B) What is the probability that at least one call arrives within 8 and 16 minutes after opening?
1. The time between calls to a corporate office is exponentially distributed with a mean of 10 minutes. (a) What is the probability that there are more than three calls in one-half hour? (b) What is the probability that there are no calls within one half hour? (c) Determine x such that the probability that there are no calls within x hours is 0.01
