Assume that a construction activity has an uncertain duratio

Assume that a construction activity has an uncertain duration (D) for competition. The duration was subjectively evaluated based on prior experiences with similar activities as an interval with a uniform distribution with a=100 and b=200 days. Determine the following probabilities: a) P(D > 100); b) P(D < 150); c) P(D=180); and d) P(120<D<200).
