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

$\backslash$table$[[$ACtivity$,$Tepestate,TWRES $($Dars$)],[$pebecessors$,2,$m$,$b$],[-,1,4,7],[$b$,-,1,6,11],[$C$,$A$,2,6,7],[6,$A$,3,2,13],[$E$,8,1,2,6],[$F$,$C$,0,1,5,9],[6,$D$,$ E$,1,2,9],[$H$,$F$,6,3,6,5]]$

b$.$ What is the critical path?

B$.$E$-$GH

A$-$D$.$GH

A$.$D$.$F$-$H

AC$.$F$.$H

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

Note: Do not round intermediate calculations. Round your anver is $3$ detimat places.

Project completion time

$6.$

d$.$ What is the probability of completing this project within $23$ days?

Note: Use Excel's NORM.S$.$DISTO function to find the correct probability for your computed Z value. Do not round intermediate calculations. Round $"x"$ value to $2$ decimal places and final answer to $4$ decimal places.
