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		0.25
		6		0.35
		7		0.25
		8		0.15
B		3		0.20
		5		0.55
		7		0.25
C		10		0.10
		12		0.25
		14		0.40
		16		0.20
		18		0.05
D		8		0.60
		10		0.40

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

Use the random numbers 0.1778, 0.9617, 0.6849 and 0.4503 to simulate the completion time of the project in weeks.

Activity	Random Number	Completion Time
A	0.1778	__weeks
B	0.9617	__weeks
C	0.6849	__weeks
D	0.4503	__weeks
Total		__weeks
