PERT is probabilistic in nature.
CPM is deterministic in nature.
CPM is event-oriented.
CPM and PERT use similar terminology but were developed independently.
Only one arrow defines each activity.
A network must have only an initial and only one terminal node.
Final nodes and identical initial can identify two activities.
Its free float is three days.
Its independent float is 0.
It is a critical activity.
The ES of this activity is 8.
Interfering float = Total float – Free float
Total float =Free float + Independent float
Total float ≥ Free float ≥ Independent float
Free float = Total float – Head event slack
Always pay attention to the critical path and select between critical activities only.
Crashing cost per day = (Crash cost – Normal cost) / (Normal time – Crash time).
Always choose the activity with the least crashing cost.
All are true

A project can be called a set of activities that can be performed in a particular logical sequence.
An activity cannot be represented by more than one arrow, but an arrow can represent one or more activities.
An arrow which is representing an activity may have any kind of length and shape.
All are correct
All the predecessor(s) of an activity should be focused on.
Should only focus on immediate predecessor(s).
Should drop redundant predecessors.
All of these
