Three Stat 110 students are working independently on this pset. All 3 start at 1 pm on a certain day, and each takes an Exponential time with mean 6 hours to complete this pset. What is the earliest time when all 3 students will have completed this pset, on average? (That is, all of the 3 students need to be done with this pset.)

Solution:
11 hours. (Label the students, consider the minimum of exponentials and use the memoryless property). See iTunes course for detailed solution.
