This article presents 2 unexpected probabilities. If there are at least 23 people in a class, then the probability that there is a shared birthday exceeds one half. This is explained by the idea of complementary events. What are the chances of there being a student who ends up in the same seat when everyone in the class is reseated? This probability is arount 2/3 irrespective of the number of students, and was solved by Montmort(1708).
