In PERT project estimation, the expected activity duration ($T_e$) is calculated using Optimistic ($a$), Most Likely ($m$), and Pessimistic ($b$) estimates as:

A$T_e = rac{a + 4m + b}{6}$

B$T_e = rac{a + m + b}{3}$

C$T_e = rac{a + 2m + b}{4}$

D$T_e = rac{a + 6m + b}{4}$

Explanation

PERT uses a weighted beta distribution formula $T_e = rac{a + 4m + b}{6}$ to calculate expected task duration.
