With probabilistic time estimates, when we calculate the expected time for an activity, we treat each activity time estimate as a random variable derived from a ______________ probability distribution.
A) normal
B) beta
C) gamma
D) Poisson
E) uniform

Question

Quizplus · Accepted Answer

When using probabilistic time estimates, a Beta distribution is typically used to model the range of possible outcomes for an activity duration. This distribution considers both the best and worst-case scenarios for an activity and the likelihood of each scenario occurring. The use of a Beta distribution allows for a more accurate estimation of the expected duration of an activity.
