EXPLANATION
First we have to calculate Expected Time using formula
Expected time = (a+4*m+ b)/6
Step 2/2
Activity on Network Diagram:
A/3B/2C/2D/3E/5F/4G/3.83H/3.83
Paths:
ACFH = 3+2+4+3.83 = 12.83
ADFH = 3+3+4+3.83 = 13.83
ADGH = 3+3+3.83+3.83 = 13.66
BEGH = 2+5+3.83+3.83 = 14.66(CRITICAL PATH)
EXPLANATION
Based on the given information Activity on network diagram and critical path
the path which is having highest duration is critical path.
Final answer
Activity on Node Network Diagram:
A/3B/2C/2D/3E/5F/4G/3.83H/3.83
b.
the critical path is BEGH
Choose 1st option.
C.
The Expected project completion time is 14.66 days
