WebOct 5, 2024 · We will calculate how 3 people out of n doesn’t share a birthday and subtract this probability from 1. All n people have different birthday. 1 pair (2 people) share birthday and the rest n-2 have distinct birthday. Number of ways 1 pair (2 people) can be chosen = C (n, 2) This pair can take any of 365 days. 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.
