understandinguncertainty.org 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.

Some years ago I used to pick up/drop off, on my drive to work, two colleagues. One evening Sue was a little late coming to my car. Val and I chatted for a few minutes, and when Sue eventually arrived she apologised saying that she was late as it was Phil's birthday that day (a person working in her department). I replied by saying, "Of coarse it is, Phil and I share the same birthday, exact to the day." It was my birthday that day. Sue said, "That's odd, it's my birthday today as well." (Half my age though). There was a "Hey you two, are you trying to wind me up?" from Val on the back seat, "It's my birthday as well today." Three people, in the same car, with the same birthday - of 14th September!!!
