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:

1.?Provide the base-case, worst-c ase, and best-case calculations for the time to complete the project.

2. Use the random numbers 0.2383, 0.6426, 0.9677 and 0.2478 to simulate the completion time of the project in weeks.

Activity Time (weeks) Activity Probability 0.31 0.32 0.24 0.13 2 0.24 0.54 0.22 15 17 19 21 23 0.09 0.23 0.39 0.20 0.09 0.73 7 2 0.27
