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

	IMMEDIATE PREDECESSORS	TIMES (DAYS)
ACTIVITY		a	m	b
A		1	4	7
B		2	3	7
C	A	3	5	7
D	A	5	6	10
E	B	1	2	6
F	C,D	1	3	6
G	D,E	1	3	14
H	F,G	2	5	14

b. What is the critical path?

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