QA002 : The optimum time (O), most likely time ( M), pessimistic time ( P - in days ) _________

Solution : 

The expected completion time is calculated by _

                                         

Now,  E-F-G-H-I  is the critical path here.

Now, Calculate the expected time for each activity 

For,                        E-F  expected Time 

                                                         

Simillarly,             for F-G, expected time = 8.16

                              for G-H, expected time = 7.16

                              for H-I, expected time = 12.16

Hence, expected completion time for the project = sum of all expected duration of activities.

                            = 10.33+8.16+7.16+12.16

                            = 37.81 Days
