A . The probability that they would arrive on time using personal vehicles is much higher than using the metro public transportation system (MPTS)
B . The probability that they would arrive on time using the MPTS is much higher than using their personal vehicles
C . The two probabilities are about the same excepting in one case the consistency is higher than the other
D . We need to compile more data around weekends to incorporate for traffic differences
E . When Standard Deviation is higher the probability goes down and so the MPTS is worse
