The "challenge question" is the most interesting part of the post. The article you linked to in that paragraph has a lot of implications for justice systems, namely that jurors need a better understanding of probability, especially as DNA fingerprinting and similar forms of forensic evidence become more and more precise. Though the article does point out how probability can be misinterpreted or skewed by both the defense and prosecution, jurors would be better prepared to assess such arguments if they had a better intuitive understanding of probability theory.
