Same Birthday

As of the 23rd May 2022 this website is archived and will receive no further updates.

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.

I am one of 3 children (all boys) all born on July 8th, my Brothers Robert born 8.7.1939, Anthony 8.7.1943 and myself David 8.7.1947. I read in the Mail on Sunday that 2 people with the same birthday is 1 in 35000 so would like to know what our chance was. I have not heard of any living or dead family having 3 children all born on the same date.
