Description

(Same video without the music: https://youtu.be/sz5oLEpc8xE) This problem involves 100 red balls, 100 blue balls, and 2 urns. First you distribute all the balls between the 2 urns, placing at least 1 ball in each urn. Next, you select an urn at random, and then draw a ball at random from the urn. You win $100 if you draw a red ball. What is your best strategy for distributing the balls, and what is your winning percentage? The video presents the solution and a proof of its optimality. Do you like the music in this video? Let me know what you think! I'm deciding whether to add music to videos I make. If you don't want music, I made a version of this video without background music just for you: https://youtu.be/sz5oLEpc8xE
