Rolling the Dice

In math today, we played a new game with dice. We rolled two dice. One was a normal die, with the numbers 1, 2, 3, 4, 5, and 6. The other die had the numbers 7, 8, 9, 10, 11, and 12 on it. Every time we rolled the dice, we added the two numbers together. We kept track of which ones we rolled with a bar graph, to see which one we rolled the most.

At the end of math, we put all of our data together to make a class graph of our results. We learned that the best way to test probability is to get lots of information, lots of data.

We had a few questions.

Why were there no 7's?

Why are the numbers in the middle the most likely sums?
