This is a modification of Joseph Delgadillo's excellent tutorial (Matlab from Beginner to Advanced on YouTube and also at teachable.) that computes and plots the probability of two or more people in a random group of n people will have the same birthday. Surprisingly, the probability is 0.5 at around 23 people, and approaches certainty after around 50 people. Cool problem, and thanks to Joseph Delgadillo for the very best Matlab tutorial on the Web. Great course.
