Given an expected project completion time of 26 weeks and a project variance of 9 weeks, what is the approximate probability of completing the project within 20 weeks (Tc)? Pick the closest answer from provided options.

Normal distribution table is available on BB/Course Documents or can be computed using Excel

Z=(Tc - Te)/Project std deviation, where Tc = desired project completion time; Te = expected project completion time;

Std deviation = Sq root of Variance
