Della works as a project manager for Tech Perfect Inc. She is studying the documentation of planning of a project. The documentation states that there are twenty-eight stakeholders with the project. W

Applying the standard PMI formula n(n-1)/2 with n=28 gives 28 x 27 / 2 = 756 / 2 = 378, which correctly represents the total number of unique pairwise communication paths among all 28 project stakeholders.

300 does not result from applying the formula n(n-1)/2 to 28 stakeholders and has no mathematical basis in the standard communication channels calculation.

28 is simply the count of stakeholders, not the number of communication channels; the pairwise combination formula must be applied to determine the total channel count.

250 does not result from any standard formula applied to 28 stakeholders and is mathematically incorrect for this calculation.
