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.

Daily Mail gets odds right shock

The Daily Mail and other papers carried the story about the Banwell family whose third child shares a birthday, February 5th, with two older siblings, and this time they got the odds right at 133,000 to 1!

Coincidence odds are wrong yet again

The Sun today features a story about a family who have had three children all born at 7.43 (two am and one pm). Heartwarming, but the quoted odds of 300,000,000 to one are sadly wrong.

Strange how these "1 in 48,000,000" events keep on happening!

The Daily Mail has a story today about the Allali family whose third child was born on the same date as his two older siblings, claiming that "mathematical experts have revealed that the three siblings have beaten odds of 48 million to one". If these are the real odds, isn't a bit strange how often this story appears in the papers?
