The Cretin 3.5 program is divided into 3 blocks that are being compiled on 3 different computers (in parallel). Each block takes an Exponential distributed amount of time to compile, 5 minutes on the average. The time required to compile 1 block is independent of the time to compile the other blocks. The program is completed when all the blocks are compiled. 1. [5 pts] Compute the probability that the parallel compile of Cretin 3.5 will take 7 mins or less. 2. [6 pts] Compute the probability that the parallel compile of Cretin 3.5 will take more than 10 minutes
