Question
You arrive to the class with a delay of time T,. The professor arrives to the class
with a delay of time T,. Both T, and T, are exponential variables with parameter
lambda. Both T, and T, are independent. Let the difference in time T = T, - T2.
1. Find the CDF of T when T > 0.
2. Find the CDF of T, when T < 0, based on your answer to the previous part.
(Do not recompute the answer from scratch, for example, by integration)
3. Using the CDF, you derived in subparts 1 and 2, write down the PDF of T.
