What to Study?
| 1. | How many communication channels are added when you add three people to a four person team? |
| Answer: 15 communication channels are added. | |
| No. of channels for a 4 person team: (n*(n-1))/2 (4*3)/2 = 6 | |
| No. of channels for a 7 person team: (7*6)/2 = 21 | |
| Therefore, adding 3 people to a 4 person team increased the no. of communication channels by 15. (21-6) | |
