Probability Results Report lets you peruse the historical results from all the probability games.

Note: Probability is a funny thing. Don't expect the numbers from trials to exactly match the predicted results--especially if you run only a few trials. As you run more trials the numbers should tend to get closer to the predictions. After a couple of hundred runs, you should see results that are at least vaguely close to expectations. However, even after thousands of runs you might still see some anomalies.
