Remembering everything you ever

learned about probability, what is the

likelihood that both paths complete in $18$

days or less? Enter your answer as a

probability, rounded to $4$ decimals $(0\mathrm{.}1234$ ;

not $12\mathrm{.}34$ or $\mathrm{.}1234).$

Both Paths probability: Using the table below, sketch out an AON

Network using the average or mean time

estimates for each task, and calculate the

critical path$($s$)$ using mean task times.
