Problem 3 (3 POINTS) Building a backyard swimming pool consists of nine major activities. The activities are as shown in the network diagram. Note: There are 3 paths in this network Assume the activity time estimates (in days) for the swimming pool construction project are as follows: Activity Optimistic (o) Most Likely (m) Pessimistic (p)

ACTIVITY	OPTIMISTIC(0)	MOST LIKELY(M)	PESSIMISTIC(P)
A	3	5	6
B	2	4	7
C	5	6	7
D	7	9	11
E	2	6	8
F	2	5	7
G	5	6	8
H	6	8	10
I	3	4	6

What is the probability that the project can be completed within a deadline of 18 days? Assumption: If the z-value of a path is greater than or equal to 3, then there is a 100% probability that the path will be done as per its expected time.

problem) Hint: There are THREE paths in this network (I am giving this information so that you minimize your errors). B A D > E F END G H
