was produced by the Winton programme for the public understanding of risk based in the Statistical Laboratory in the University of Cambridge. The aim was to help improve the way that uncertainty and risk are discussed in society, and show how probability and statistics can be both useful and entertaining.

Many of the animations were produced using Flash and will no longer work.

iconThis is really a quincunx made to look like lightning for a bit of fun. The lightning has to make 20 left or right choices on its way to the ground. If the stick man stays put he has a 1 in $2^{20}$ chance of being struck on each flash. That's roughly one micromort. As the strikes hit the ground the number of hits in each place appears as a bar chart.

You can access the animation in a large window here. If you click on the animation and then use the arrow keys you can move the stick man into a more dangerous zone.

This animation needs Flash player 10.
