For projects whose activities have probabilistic time estimates, the probability of completing the project in a specified amount of time is determined by __________________________.
A) the expected time for the critical path only
B) the standard deviation for the critical path only
C) the expected time and standard deviation for the critical path only
D) the expected times for all paths
E) the expected times and standard deviations for the critical path and paths whose expected times are close to that of the critical path

The probability of completing the project in a specified amount of time should take into account not only the critical path but also other paths that have similar expected times. Hence, the best choice is E, which considers the expected times and standard deviations for the critical path and paths whose expected times are close to that of the critical path. This approach provides a more accurate and comprehensive assessment of project completion probabilities.
