(d) If the athletic director plans to start the project on January 1, calculate the probability the track and field team will be ready by the scheduled April 1 date (13 weeks) based solely on the critical path. (Round your answer to four
decimal places.)
0.0951
Should the athletic director begin planning the track and field team before January 1? (The probability for finishing on schedule should be at least 0.9.)
Since the probability that the track and field team will be ready by April 1 is less
than 0.9, the athletic director should
begin planning before January 1.
