Problem 5

Using the following project information, calculate the expected time for each of the project activities.

Activity		Optimistic Time Estimate(weeks)		Most Likely Time Estimates (weeks)		Pessimistic Time Estimates (weeks)		Immediate Predecessor(s)
A		2		6		9		none
B		4		6		7		A
C		4		7		12		A
D		5		5		10		B

F		4		5		5		D,E
G		4		5		10		D,E
H		4		6		11		F
I		6		9		12		G
J		3		3		3		H,I
