If the optimistic time, most likely time and pessimistic time for activity A are 4, 6 and 8 respectively and for activity B are 5, 5.5 and 9 respectively, then
A. expected time of activity A is greater than the expected time of activity B
B. expected time of activity B is greater than the expected time of activity A
C. expected time of both activities A and B are same
D. none of the above
Answer: Option C

Expected time of Activity A = (4+6*4+8)/6=36
Expected time of Activity B = (5+5.5*4+9) = 36
Hence, the Expected time of Activity A and B are same.
