There are 50 stakeholders in the current project. How many communication channels exist in this project?

1200 results from incorrectly using 50 x 48 / 2, substituting n-2 instead of n-1 in the formula.

Applying the formula n(n-1)/2 with 50 stakeholders yields 50 x 49 / 2 = 2450 / 2 = 1225 communication channels. This formula counts every unique pair of stakeholders as a potential communication path, and it is a standard project communications management calculation tested on certifications such as PMP and CompTIA Project+.

1500 does not result from any correct application of the formula and likely comes from an arithmetic error such as 50 x 30 = 1500.

500 results from an incorrect calculation such as 50 x 20 / 2 = 500, which does not follow the n(n-1)/2 formula.
