Expected completion time
Expected completion time is given by: a+4b+c6
Where a is the optimistic time, b is the most likely time and c is the pessimistic time.
Variance for each activity = :(c- a6)2
Activity 1→Activity 2 → Activity 5 → Activity 6 → Activity 7
Duration of the project = duration of the critical path = 80.5 days
Probability of completion within 40 days
Total variance for the project = 55.278
Standard deviation of the project = 55.278 = 7.435
Average completion time = 80.5 days
Probability of completing the project within 40 days:
X = 40
Z = 40-80.57.435 = -5.447
The Z-value above is less than -3.90 hence the p-value is zero. Therefore, the probability of completing the project within 40 days or less is zero (0).
