Final answer:
To find the number of communication paths in a group of n people, use the formula C = n(n-1)/2.
Step-by-step explanation:
To find the number of communication paths in a group of n people, we use the formula:
C = n(n-1)/2
Where C represents the number of communication paths and n represents the number of people in the group.
For example, if there are 5 people in a group, we can find the number of communication paths as follows:
C = 5(5-1)/2 = 5(4)/2 = 10.
