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.

My gran had five kids. The first had three boys, the second had two boys, the third had two girls, the fourth had two girls and the fifth had one girl and one boy. Each of her five children had one left handed child, and one right handed. Unfortunately I don't know about the very first grandchild.
