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

$b.$ What $is$ the critical path?

$B-E-G-H$

$A-D-G-H$

$A-D-F-H$

$A-C-F-H$

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

Note: $Do$ not round Intermedlate calculatlons. Round your answer $to3$ decimal places.

Project completion time $,19\mathrm{.}500$ days

$d.$ What $is$ the probability $of$ completing this project within $20$ days?

Note: Use Excel's NORM.$S.$DIST$()$ functlon $to$ find the correct probabllity for your computed $Z-$value. $Do$ not round Intermedlate

calculations. Round $"z"$ value $to2$ decimal places and final answer $to4$ decimal places.
