A project has four activities (A, B, C, and D) that must be performed sequentially. The probability distributions for the time required to complete each of the activities are as follows: Activity Activity Time (weeks) Probability A 5 0.25 6 0.35 7 0.25 8 0.15 B 3 0.20 5 0.55 7 0.25 C 10 0.10 12 0.25 14 0.40 16 0.20 18 0.05 D 8 0.60 10 0.40 Provide the base-case, worst-case, and best-case calculations for the time to complete the project. Activity Base case Worst case Best case A weeks weeks weeks B weeks weeks weeks C weeks weeks weeks D weeks weeks weeks Total weeks weeks weeks Use the random numbers 0.1778, 0.9617, 0.6849 and 0.4503 to simulate the completion time of the project in weeks.
