PERT is commonly used in the construction work.
PERT is suitable for the estimation of activity duration where high levels of uncertainty is there.
PERT does not provide time duration.
PERT is a deterministic approach. for estimating the time duration of an activity.

Answer 1

Explanation:

Programme Evaluation and Review Technique (PERT):

Pert was developed by the U.S. Navy during the late 1950s to accelerate the development of the Polaris Fleet Ballistic Missile.
PERT, is an abbreviated form that stands for, Programme Evaluation and Review Technique and is used for planning, scheduling, and monitoring the project.
Development of this weapon involved the coordination of the work of private contractors, a management consulting firm, and the Lockheed Missile System Division.
In PERT three time estimates are made.
PERT follows the probabilistic approach and absorbs the uncertainties into the time estimates for activity and project durations.
The time estimate of activity has a greater range of variation and hence greater uncertainty, therefore probabilistic approach is used.
In PERT time is directly proportional to time hence minimum cost will be achieved corresponding to minimum completion time.
PERT is suitable for new projects.
In PERT each activity follows β distribution.

Hence option (2) is the correct answer.
