When rolling a pair of dice, the roll should come up 11 once every 18 rolls, or 5.6% of the time. You decide to test this out, rolling 40 times a day every weekday, and using the weekend to analyze the data. As the table shows, with the exception of Friday, every day you rolled either double the expected number of 11s, half the expected number of 11s or no 11s at all. Yet the average for all the days is 5.5%, virtually identical with the theoretical number. How do you explain this?
