Events and Probability Spaces · Birthday Paradox

Lesson 2

Nikolai Chukhin · Alexander S. Kulikov

Problem. Thirty-five people came to a discrete mathematics lecture. We would like to find the probability that among them there are at least two with the same birthday (assuming that each of them has a birthday on a random one of 365 days). Test your intuition: which of the options is the closest estimate of the probability?
