Urn

An urn is a container used to hold and sometimes dispense items, often used in contexts like drawing lottery or raffle tickets, or storing ashes of a deceased person. In probability and statistics, an urn is a theoretical model where objects such as balls or tickets are drawn randomly, helping us analyze outcomes and chances systematically. Think of it as a box that holds different items, with procedures to randomly select or replace them for study or decision-making.
