Where do 170 and 10,000 come from? What if those 170 friends are all friends with each other?




If I have 170 friends on average, why don't my friends also have an average of 170 friends? (170 * 170 â‰ 10000)



Each of my 170 friends has on average 10000/170 friends? Why am I so much less popular than my friends?




Am I below average in the number of friends? Can I and my friends really reach 10,000 people?






How many friends does each of your 170 friends need to have so they would have 10,000 friends?
