WebMay 15, 2024 · The Birthday problem or Birthday paradox states that, in a set of n randomly chosen people, some will have the same birthday. In a group of 23 people, the probability of a shared birthday exceeds 50%, while a group of 70 has a 99.9% chance of a shared birthday. We can use conditional probability to arrive at the above-mentioned … WebThen the probability of at least one match is. P ( X ≥ 1) = 1 − P ( X = 0) ≈ 1 − e − λ. For m = 23, λ = 253 365 and 1 − e − λ ≈ 0.500002, which agrees with our finding from Chapter 1 that we need 23 people to have a 50-50 chance of a matching birthday.
