A supermarket chain is considering opening a supermarket in Grenada.

Draw the project network diagram.
Calculate the expected duration and variance of all activities.
Determine the earliest start (ES), latest start (LS), earliest finish (EF), and latest finish times (LF) for each activity.
Calculate the slacks and determine all critical paths and critical activities
What is the probability that the project will be completed within the 26-week time frame?
