Overview: Is it possible to predict the outcome of Britain's National Lottery? Derren Brown did just that on Wednesday night. In Friday's extraordinary show he revealed three possible ways he may have been able to do that. He began with the science of mathematics and probability. Is there a pattern in the numbers? A numerical code that could unlock good fortune? Next his investigation continued into the world of intuition and the wisdom, and sometimes madness, of crowds. What influence on the outcome can the players themselves have? Finally, Derren explained what he definitely did not do. Is it possible to control the outcome of the lottery using more devious means? In other words, can you rig the world's most secure lottery? And if so, how would you go about it?
