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		0.30
		6		0.34
		7		0.26
		8		0.10
B		4		0.19
		6		0.51
		8		0.30
C		12		0.08
		14		0.22
		16		0.41
		18		0.16
		20		0.13
D		9		0.67
		11		0.33

1. 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

2. Use the random numbers 0.6168, 0.7203, 0.4178 and 0.4582 to simulate the completion time of the project in weeks.

   Activity	Random Number	Completion Time
   A	0.6168	weeks
   B	0.7203	weeks
   C	0.4178	weeks
   D	0.4582	weeks
   Total		weeks
