Abstract
I will give an introduction to probabilistic combinatorics and graph theory. The star of the story will be the Erdos-Renyi random graph, a graph on n vertices in which every edge is included with probability p. I will explain some of the reasons why this model has attracted so much attention in combinatorics in the last 60 years and describe its connections to computer science and physics.
