Use the below PERT info to answer the following questions. TIMES (DAYS) IMMEDIATE ACTIVITY PREDECESSORS a m b A 8 15 20 B A 4 7 18 C A 5 7 15 C 4 5 12 E B, D 4 7 11 a. What is the expected project completion time? Do not round intermediate calculations. Round your answer to 2 decimal places. Project completion time days b. What is the percent probability of completing the critical path within 32.2 days or less? Do not round intermediate calculations. Hint: there is an Excel function that will work well for this. Enter a value like 13.85 percent as 13.85, not .1385 or 13.85%. With that format, go to two decimal places, so 13.85 percent would be entered as 13.85, not 14. Percent Probability %
