The UK National Lottery - a guide for beginners

In the early days of the UK National Lottery, it was quite common to see newspaper articles that looked back on what numbers had recently been drawn, and attempted to identify certain numbers as "due" or "hot".

Keith Ball uses information theory to explain how to cut down the number of tests significantly, by pooling samples of blood.
