Pin code coincidence

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.

Opened new bank account, they sent me a card and four digit pin. The pin was my work extension telephone number minus one! Changed pin to something a bit more secure, i.e. not related to a number I commonly use or associate with. Interesting question, how random (secure?) are our given vs chosen pin codes and is there a best strategy for choosing one? Maybe I should have stuck with the one supplied?
