Problem 3

Consider the following information about a probabilistic project:

Activity	Immediate Predecessors	Time (weeks)
		Optimistic	Likely	Pessimistic
A		2	5	8
B	A	2	8	11
C	A	4	7	10
D	A	5	10	15
E	B	5	9	16
F	C	3	6	15
G	D	8	10	12
H	E, F, G	5	5	5

1. Calculate the expected durations and the variance (or standard deviation) for each activity.
2. What is the expected project completion time and the project standard deviation?
3. What is the likelihood the project will be finished by week 32?
4. If you wanted to be 99% confident of delivering the project on time, how much additional time would you need to add to the schedule?
5. 

Problem 3 Coeatader the following informaricen ahout a peobabilistic project: a. Calculate the expectad dusations and the variance (or ktandard deviation) for each activity - b. What is the expscted project completion time and the project standard deviatiou? c. What 15 the likelihood the project will be fimisoed by week 32
