You have determined the critical path in a cpm analysis. you would like to determine the probability of completing the project is a desired period of time. one of the activities on the critical path has an optimistic time of 5 minutes, a most likely time of 6, and a pessimistic time of 17. what is the variance estimate of this activity?

The variance estimate of this activity is 4.

Step-by-step explanation:

Given information: One of the activities on the critical path has

Optimistic time = 5 minutes

Most likely time = 6 minutes

Pessimistic time = 17 minutes

The variance estimate of a activity is

where, is pessimistic time of that activity and   is optimistic time of that activity.

The variance estimate of the given activity is

Therefore the variance estimate of this activity is 4.

the sum of the lengths of any two sides of a triangle is greater than the length of the third side. if you take the three sides of a triangle and add them in pairs, the sum is greater than (not equal to) the third side. if that is not true, then it is not possible to construct a triangle with the given side lengths.
