3.45 Assume that you have a project with seven activities labeled A-G (below). Derive the earliest completion time (or early finish-EF), latest completion time (or late finish-LF), and slack for each of the following tasks (begin at time = 0). Which tasks are on the critical path? Draw a Gantt chart for these tasks. Preceding Expected Critical Activity Event Duration EF LF Slack Path? A B.
