## What is the most probable sum of random numbers

Anyone who has a dice can play a simple game. Choose a number greater than 6. Then roll the dice until the sum of the rolled numbers is equal to or greater than the chosen number.

Our minds are not used to visualizing really big numbers. Michael shows a great way to visualize 52! Enjoy.
