I'm confused whether to count Project manager as a team member. Consider the following question:

 You are the project manager. You have a team of 5 members. They communicate with each other regularly. How many communication channels are in your team:

1. 10

2. 15

I answered 15...because I added 1 for the Project manager also. but the correct answer was 10. I'm confused whether to add Project manager also or no.
