VERY HARD Puzzle: What Is The Distance Between Two Random Points In A Square?
- 6 yıl önce
What is the average distance between two randomly chosen points in a square with a side length 1? The video presents how to estimate the answer and also derives the ex answer using integrals. Per suggestions in the comments, I have modified the title to indicate the difficulty level is VERY HARD (a college level calculus course and probability theory course are necessary background).\r
