Speaker: Mihai Stoiciu

Abstract: We will discuss Bertrand’s Paradox, a famous problem in probability. The question is the following: what is the probability that a random chord in a given circle is longer than the side of the equilateral triangle inscribed in the circle? Since the problem is not well-posed, we can find at least five "correct" answers to this question. We will present these different approaches and discuss the concepts of randomness and well-posedness.
