Problem
The formula to calculate the number of communication channels for a team of five members is: 5 x (5 - 1) / 2 = 10.
This calculation means that for a team of five members, there are 10 possible communication channels. This is because each member can communicate with the other four members, leading to 4 possible channels of communication for each member. When multiplied by the number of team members, this results in the total number of possible communication channels for the team.
