In the Analytical Approach,the Probabilities of Completing the Project Within

In the analytical approach,the probabilities of completing the project within a certain time are computed assuming that ________.

A) the expected project completion time is the product of the expected activity times along the critical path,which is found using the expected activity times
B) the variance of the distribution is the sum of the variances of those activities along the critical path,which is found using the expected activity times
C) the variance of the distribution is the sum of the variances of those activities along the critical path,which is found using the variances of activity times
D) the distribution of project completion times is not known
