Problem $5-10($Algo$)$

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

b$.$ What is the critical path?

$A-D-G-H$

$B-E-G-H$

$A-D-F-H$

$A-C-F-H$

c$.$ What is the expected project completion time?

Note: Do not round intermediate calculations. Round your answer to $3$ decimal places.

$\backslash$table$[[$Project completion time$]]$

d$.$ What is the probability of completing this project within $22$ days?

Note: 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.
