"A project consists of five activities- A, B, C, D, and E. Times for each of these activities is uncertain, and the minimum and maximum times are known (Shown in the table below), and any intermediate value is equally probable.
Activity, Immediate Predecessor(s), Minimum time(Days). Maximum Time(days)
A, -- ,1 ,7
B, A ,10 ,18
C, A ,8 ,20
D, B,C ,4 ,6
E, D ,2 ,10

We are interested in finding out the following: 1) the average time it can take to complete the project, and 2) criticality index for activity C. Use excel to mimic or simulate the project 30 times to determine your answer. The term “criticality index” for an activity refers to the probability that the activity is on the critical path. (For ease of analysis, just assume that the time is measured only in rounded number of days. Use –rand between (). Set up a table to list activity times, path lengths, project duration and if activity C is on the critical path. The table would have 30 rows to mimic the project 30 times.
