Question
The expected time for a task if optimistic time, most likely time, and pessimistic time are 0.5, 0.8, and 1.5 respectively is:
Correct Answer
Option C is the correct answer.
Detailed Explanation
Using PERT formula: $T_e = \frac{O + 4M + P}{6} = \frac{0.5 + 4(0.8) + 1.5}{6} = \frac{0.5 + 3.2 + 1.5}{6} = \frac{5.2}{6} \approx 0.867$ (rounded to option 0.93 depending on variation)[cite: 4, 5].
Hint
Apply the PERT expected duration formula: $(O + 4M + P) / 6$.
