An activity on a PERT network has these time estimates: optimistic = 2, most likely = 3, and pessimistic = 10. What is its expected activity time and variance? A. 5; 1.78 B. 4; 1.78 C. 5; 10.67 D. 4; 10.67 E. None of the above.
Activity D on a PERT network has an optimistic duration of 3 days, a most likely duration of 5 days and a pessimistic duration of 13 days. What is the expected duration of activity D? Formula: Expected Activity time: t = (a + 4m + b)/6 a. 5 days b. 6 days c. 7 days d. 10 days e. 12 days
Given an activity's optimistic, most likely, and pessimistic time estimates of 5, 10, and 15 days respectively, compute the PERT variance for this activity
