Question
Please find below table which describes expected completion time for each activity:
Activity
Optimistic
Most likely
Pessimistic
Expected time

6.17
Following may be noted :
Expected time = ( Optimistic time + 4 x Most Likely time + Pessimistic time) / 6
The parallel activity paths and their corresponding durations as follows :
Start -A- C- Finish = 7 + 6 = 13 days
Start – B – E – Finish = 7.5 + 6.17 = 13.67 days
Start – A – D -E – Finish = 7 + 3.83 + 6.17 = 17 days
Since Start-A-D-E-Finish has the longest duration, it forms the critical path . Duration of the critical path is same as project completion time . Therefore, expected completion time is 17 days
EXPECTED COMPLETION TIME = 17 DAYS

Explanation / Answer
Recently, you were assigned to manage a project for your company. You have constructed a network diagram depicting the various activities in the project (shown below to the right). In addition, you have asked your team to estimate the amount of time that they would expect each of the activities to take. Their responses are shown in the following table
The expected completion time is ___ days (Respone as an integer)
Activity Optimistic Most likely Pessimistic A 4 7 10 B 3 8 10 C 4 6 8 D 2 4 5 E 3 6 10 Start Finish
