Activity Overview

In this activity, the FBI intercepted an encrypted message they believe contains a phone number that could lead to an "insider" who may be helping the poisoner. Don suggests using a computer to start trying to break the code. Charlie proposes that first they gather as much information as possible and use Information Theory to help determine how long it this might take.
