RCDD-001 Exam - Question 69


What is the PERT estimate of time for cable placement on a given job?

- Optimistic time is 100 hours

- Most likely time is 125 hours

- Pessimistic time is 210 hours

Show Answer
Correct Answer: C

To calculate the PERT estimate of time, the formula is used: (Optimistic time + 4 * Most likely time + Pessimistic time) / 6. Given the values: Optimistic time = 100 hours, Most likely time = 125 hours, and Pessimistic time = 210 hours, the calculation is as follows: (100 + 4 * 125 + 210) / 6 = (100 + 500 + 210) / 6 = 810 / 6 = 135 hours. Therefore, the PERT estimate of time for cable placement on a given job is 135 hours.

TDMM page 21-23 (1554) PERT formula is [Optimistic + (4 x Most likely) + Pessimistic] / 6 PERT = [100h + (4 x 125h) + 210h] / 6 PERT = 135h
