Problem $5-10($Algo$)$

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

ACTIVITY IMMEDIATE PREDECESSORS TIMES $($DAYS$)$

a m b

A $123$

B $147$

C A $2811$

D A $159$

E B $123$

F C$,$D $147$

G D$,$E $123$

H F$,$G $233$

What is the critical path?

multiple choice

A$-$D$-$G$-$H

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

B$-$E$-$G$-$H

A$-$C$-$F$-$H

What is the expected project completion time?

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