Question
The probability of rolling a 4 on a number cube is 1661 . If you were to roll the cube 48 times, you would expect to get a 4 around 8 times (16⋅48=8)( 61 ⋅48=8).You simulate 48 rolls. How many 4s would make you question your model?A.24B.8C.6D.10
Solution
The question is asking how many times you would need to roll a 4 in your simulation of 48 rolls to start questioning the accuracy of your model.
Your model predicts that you should roll a 4 around 8 times in 48 rolls.
If you rolled a 4 significantly more or less than 8 times, you might start to question your model.
So, the answer would be A. 24. This is significantly more than the 8 times predicted by your model, and would likely cause you to question its accuracy.
