Consider the following data for PERT Scheduling; Events and processing time (week) are as follows - A(3)-B(6)-C(11)-D(14)-E(3)-F(6)-G(3)-H(7). Here is the preceding of events - A&B can start anytime, C should come after A&B, D&E should come after C, F should come after E, G should come after D&F, H should come after F, then Finish. How many weeks a project can finish?
