Communication channels - should the PM be counted in or not?

When I calculate the number of communication channels (using formula [n * (n-1) / 2], you need number of the team members as input for the formula (n). I'm not sure whether I should count in also PM or not.

Example (made up question):

You are PM of the project with 6 persons. You have been added two additional resources... How much did communication channels increase...?

Now, should I:

A) calculate that the team has 6 team members + PM = 7 people (=n) and has increased from 7 to 9 persons (6 team members + PM + 2 new resources)

OR

B) calculate that initial team has 6 members (=n) and after 2 additonal resources it has 8 members (=n)?

I'm confused, since I found different explanation in test questions, that I used.

Tnx for help.

calculate that the team has 6 team members + PM = 7 people (=n) and has increased from 7 to 9 persons (6 team members + PM + 2 new resources)


 


So, the increase in channels by  9.

Hi


In your question, you said "You are PM of the project with 6 persons"  , key word is "WITH" so PM + 6. Also, PM is part of


If question say or there wise if we interpret , "there is a team of "  then 6
