 Contributed solutions to end of chapter exercises in <i>Introduction to Probability</i>, 2nd edition by Joe Blitzstein and Jessica Hwang. 
 
-The book contains many fantastic exercises that help develop intuition for thinking probabilistically. The authors provide solutions to some of these exercises on the book [website](https://projects.iq.harvard.edu/stat110/home), but most don't have published solutions. This repository aims to provide solutions for self-learners.
