WebAug 15, 2024 · The probability of two people having the same PIN on their bank card is 1 in 10,000, or 0.01%. It would only take a group of 119 people however, to have odds in favour of two people having the same PIN. Of course, these numbers assume a randomly sampled, uniform distribution of birthdays and PINs.

WebThe birthday attack is named after the birthday paradox. The name is based on the fact that in a room with 23 people or more, the odds are greater than 50% that two will share the same birthday. Many find this counterintuitive, and the birthday paradox illustrates why many people's instinct in probability (and risk) is wrong.
