A project has activities A, B, C, D as its critical activities with 'A->B -> C-> D' as its critical path. The expected values and variances of activities A, B, C, D in weeks are: A (exp value =15, var = 3 ); - 1 B (exp value =14, var = 3 ); = C (exp value =10, var = 2 ); - D (exp value =10, var = - 1). - The probability that this project can be completed in 55 weeks lies in this range: Select one: O 0% to 34% O 35% to 40% O 60% to 65% O 82% to 87% O 93% to 96% O 97% to 100%
