Question

A 6-sided dice is rolled 15 times, and somehow they get 20. What does 20 mean in the problem?

a. Outlier in the data
b. Mathematical error
c. Statistical anomaly
d. Impossible result

Answer 1

Assuming the sum of the outcomes of the dice rolls is equal to 20, this is an outlier in the data, as this requires getting a 1 or 2 on almost every roll. So, the answer is a.

Answer 2

Getting a total of 20 after rolling a 6-sided die 15 times is an impossible result, because the minumum possible score is 15 and the maximum is 90. It indicates a mathematical error.

Step-by-step explanation:

If a 6-sided die is rolled 15 times and they somehow get a total of 20, this would be an impossible result. When rolling a 6-sided die 15 times, the minimum score obtainable (if each roll was a 1) would be 15, and the maximum score (if each roll was a 6) would be 90. Therefore, the sum of 15 rolls cannot be 20. The statement about getting a total of 20 is indicative of a mathematical error in the interpretation or recording of the dice rolls. Each die roll has 6 possible outcomes, so a single roll cannot yield a 20, nor can the total of 15 rolls do so under normal circumstances.
