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

	IMMEDIATE PREDECESSORS	TIMES (DAYS)
ACTIVITY		a	m	b
A		1	5	9
B		1	2	3
C	A	3	5	7
D	A	1	4	10
E	B	1	2	3
F	C,D	1	2	12
G	D,E	1	6	8
H	F,G	2	3	8

b. What is the critical path?

A-C-F-H

B-E-G-H

A-D-G-H. Correct answer

A-D-F-H

c. What is the expected project completion time? (Do not round intermediate calculations. Round your answer to 3 decimal places.)

18.667 correct answer

d. What is the probability of completing this project within 20 days? (Use Excel's NORM.S.DIST() function to find the correct probability for your computed Z-value. Do not round intermediate calculations. Round "z" value to 2 decimal places and final answer to 4 decimal places.)
