Problem 5-10

The following represents a project that should be scheduled using CPM:

	IMMEDIATE PREDECESSORS	TIMES (DAYS)
ACTIVITY		a	m	b
A		1	4	7
B		3	5	10
C	A	2	5	8
D	A	4	6	11
E	B	1	2	3
F	C,D	3	5	7
G	D,E	1	2	6
H	F,G	2	5	6

b. What is the critical path?

	B-E-G-H
	A-D-G-H
	A-D-F-H
	A-C-F-H

c. What is the expected project completion time? (Round your answer to 3 decimal places.)

Project completion time days

d. What is the probability of completing this project within 22 days? (Do not round intermediate calculations. Round your answer to 4 decimal places.)
