The Friendship Paradox is the observation that your friends, on average, have more friends than you do. This phenomenon, which was first observed by the sociologist Scott L. Feld in 1991, is mathematically provable. In this episode of FAMUS, we will discuss the "paradox", sketch its proof, and explore some applications. The idea for the talk was inspired by a post by Richard Green on Google+.

This talk was given at the Northern Arizona University Friday Afternoon Mathematics Undergraduate Seminar (FAMUS) on Friday, September 11, 2015.
