Question Analysis:
We are given the optimistic, pessimistic, and most likely time estimates for a PERT activity. PERT (Program Evaluation and Review Technique) is a statistical tool used in project management to analyze and represent the tasks involved in completing a project. The expected time of an activity can be calculated using the formula: expected time = (optimistic time + 4 * most likely time + pessimistic time) / 6.
Calculation:
Given: Optimistic time (to) = 3 days, Most likely time (tm) = 10 days, Pessimistic time (tp) = 8 days.
Using the formula: expected time = (to + 4 * tm + tp) / 6
Substituting the given values: expected time = (3 + 4 * 10 + 8) / 6
Simplifying the expression: expected time = (3 + 40 + 8) / 6
Further simplifying: expected time = 51 / 6
Dividing: expected time = 8.5 days
Therefore, the expected time for this activity is 8.5 days.
Answer:
The correct answer is option D) 8.5 days.
