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		3		0.30
		4		0.33
		5		0.26
		6		0.11
B		7		0.19
		9		0.55
		11		0.26
C		15		0.10
		17		0.22
		19		0.44
		21		0.20
		23		0.04
D		8		0.66
		10		0.34

A. 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

B. Use the random numbers 0.8634, 0.8928, 0.7531 and 0.7648 to simulate the completion time of the project in weeks.

Activity	Random Number	Completion Time
A	0.8634	-------weeks
B	0.8928	-------weeks
C	0.7531	--------weeks
D	0.7648	--------weeks
Total		----weeks
