Determine the expected project completion time and the critical path/s. What is the probability that PFIS will finish the project within 42 days? What is the probability that PFIS will take more than 47 days to complete the project? What is the probability that PFIS will take more than 44 days but less than 51 days to comp the project? If Jonna wants to complete the project with a 97.6% assurance, then how many days from i due date should she need to start the project? You can leave your answer in decimals. f)
