Question

An activity on a project schedule has these duration estimates: optimistic (a) = 1, most likely (m) = 2, and pessimistic (b) = 5. The activity’s expected duration is:

Answer 1

Answer:

Activity expected duration = 2.333

Explanation:

Given:

Optimistic (a) = 1

Most likely (m) = 2

Pessimistic (b) = 5

Activity’s expected duration = ?

Computation of Activity expected duration:

$Activity\ expected\ duration = \frac{(a + 4m + b)}{6}$

Activity expected duration = [1 + 4(2) + 5] / 6

Activity expected duration = [1 + 8 + 5] / 6

Activity expected duration = [14] / 6

Activity expected duration = 2.333
