How is the number of potential communication channels calculated?

  1. n(n-1)/2

  2. n(n+1)/2

  3. n^2

  4. 2n

The correct answer is: n(n-1)/2

The number of potential communication channels in a project team is calculated using the formula n(n-1)/2, where 'n' represents the number of people in the team. This formula is derived from the concept that each team member can potentially communicate with every other team member except themselves. Therefore, by multiplying the total number of team members (n) by the total number of team members minus one (n-1) and dividing by two, we account for every possible communication channel while eliminating duplication. This formula ensures an accurate calculation of the potential communication channels within a project team.
