Circle Around

You and a partner should each tally results of tossing two dice 100 times.

Each person should toss two dice 50 times, tallying the sum
of the two dice each time. Next, combine your results, so you have
a frequency for each possible sum. Now make a circle graph of your findings.

After constructing your graph, answer the following questions:

Which sum was the most frequent? Which sum was the least frequent? Did any of the sums appear about the same number of times?
