Problem 12-09 (Algorithmic)

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		0.29
		4		0.38
		5		0.29
		6		0.04
B		7		0.22
		9		0.53
		11		0.25
C		9		0.05
		11		0.24
		13		0.36
		15		0.19
		17		0.16
D		10		0.59
		12		0.41

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

   Note that the answer for base case in part A were wrong. I only need the answer for base case. Thank you!
