Birthday Problem

Enrichment Powerpoint Presentation

Birthday Problem

Takes students in gradual steps through the birthday problem. Pigeon hole principle and factorial notation are explained as we arrive at the conclusion that a group of 23 people ensures that it is more likely then not that 2 of them will have a birthday on the same day. Opportunity to use spreadsheets. This works well after the "Tower of Hanoi" where extensive use is made of factorial notation towards the end.
