Dice Graph

I was curious how big the difference would be between rolling and adding three dice or rolling four dice and adding the highest three. These are two of the most common methods for generating character stats in D&D. I knew that three dice would give me a bell curve, but I had no idea what the highest three of four would look like. I used Numbers to make a graph of the probabilities, and posted them here in case anyone else was curious.

probability of rolling various numbers on three dice added together versus on four dice, with the highest three added.
