I’m sure most of have heard of the birthday paradox: the chance of two people sharing the same birthday is above 50 percent as soon as you have x people in the same room (not going to spoil the number here for those who haven’t heard of it). I’m also pretty sure, though, you haven’t seen an explanation of it that is so comprehensible (and charming) as this one by The Pudding.
