Multiple choice

The expected time (te) of a PERT activity in terms of optimistic time (t0), pessimistic time (tp) and most Likely time (tl) is given by

  1. te = $\frac{t_o + 4t_1 + t_p}{6}$
  2. te = $\frac{t_o + 4t_p + t_{p1}}{6}$
  3. te = $\frac{t_o + 4t_1 + t_p}{3}$
  4. te = $\frac{t_o + 4t_1 + t_1}{3}$
