1. Draw the AON network.
2. What is the critical path?
3. How long will it take to complete the project?
4. Can Activity B be delayed without delaying the completion of the project? If so, how many days?

Given the table above and estimated activity times below

Activity	Optimistic	Most Likely	Pessimistic
A	6.5	7.5	14.5
B	8.5	10.5	12.5
C	2.5	3.5	4.5
D	5.5	6.5	8.5
E	3.5	6.5	9.5
F	5.5	7.5	9.5
G	3.5	4.5	6.5
H	4.5	5.5	7.5

1. What is the probability that the project will be completed within (based on the path with the longest expected time)?
   1. 22 days?
   2. 23 days?
   3. 26 days?
