Instructions

Shown below is a network grown according to the preferential attachment model described in the video.  At this stage there are 9 pages (nodes) in the model.  Recall that there are two ways for the tenth node to decide which page to link to.  Either it chooses a page at random, or it chooses a page with a probability proportional to the number of the in-links that page has.
