Questions from William Heathcote Solutions for Chapter: Evidence, Exercise 3: Testing a die with Hints & Solutions
With a perfect die you should have an equal chance of rolling any of the numbers on its faces. A weighted die has an increased chance of rolling one of the numbers (often a six).
If you take a die and roll it once, does this tell you anything about whether it is weighted or not?
With a perfect die you should have an equal chance of rolling any of the numbers on its faces. A weighted die has an increased chance of rolling one of the numbers (often a six).
If you now roll it six times, the chances that each roll will give you a different number are about 1.5%. Does this mean that the die is weighted?

If you now roll it six times, the chances that each roll will give you a different number are about 1.5%. Does this mean that the die is weighted?
If you then roll the die more times and record the results in a table, how many times would you need to roll the die before you had enough evidence to say whether the die is weighted?
