Develop a project network.  Determine the expected project completion time.  What is the probability that the project completion time will be completed? With in 2 weeks earlier than the expected project completion time?  With in 1.5 week more than the expected project completion time ?

A project has the following activities, with specified precedents and expected durations (in days). What is the expected project duration?

Three activities are candidates for crashing on a project network for a large computer installation (all are, of course, critical). Activity details are in the following table: Normal Activity Time (days) A B с 7 4 11 Crash Time (days) 6 2 9 Normal Cost $5,000 $1,400 $4,200 Total Cost with Crashing Immediate Predecessor(s) $5,500 $3,100 $6,200 A
