B. Critical path
C. PERT activity
D. Critical Path Method		I. Follow B distribution
II. Built on activity oriented diagram
III. Constructed only to establish sequence
IV. Has zero total slack

If 'A' is the optimistic time, 'B' is the pessimistic time and 'C' is the most likely time of an activity, then the expected time of activity is:
Arrange the following elements of a feedback control loop in the correct order: (A) Actuator (B) Error detection (C) Controller (D) Feedback sensor Choose the correct answer from the options given below:
Which one of the following is the excess of variable time over the activity time when all jobs start as early as possible?

Consider the network diagram shown in Figure. The time estimates in days along the arrows represents the activities. The project completion time in days based on critical path is

Activities A, B, C, and D form the critical path for a project with a PERT network. The means and variances of the activity duration for each activity are given below. All activity durations follow the Gaussian (normal) distribution, and are independent of each other. 

The probability that the project will be completed within 40 days is _________ (round off to two decimal places).
