Question: The main difference between the two types (ADM, arrow diagramming method, and PDM, precedence diagramming method) of the critical path method (CPM) of scheduling is:

The main difference between the two types (ADM, arrow diagramming method, and PDM, precedence diagramming method) of the critical path method (CPM) of scheduling is:

a. Placement of the activity on the logic diagram line.

b. Arrow diagramming method (ADM) is a deterministic method, whereas the precedence diagramming method (PDM) is a probabilistic method.

c. Precedence diagramming method (PDM) is a deterministic method, whereas the arrow diagramming method (ADM) is a probabilistic method.

d. Precedence diagramming method (PDM) is a more accurate method.
