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.

Hi, in our family out of 6 children 3 were born on the 9th of the month. My sister in law and my cousin had 2 sons on the same day (9th january). I have one child born on the 9th (February) one on the 8th (November) both came late, I am now expecting my third. It's due on the 2nd of July, what's the chances of it being born on the 7th to fall in line with the others?
