**Q3: **

James has bought a tetrahedral die that has the values 1 to 4 on its faces.
He wants to investigate whether the die is fair, so he decides to roll it 100 times and record all the values in a table. He gets the following results.

What is the theoretical probability of rolling a 2, assuming that the die is fair?

What is James’s experimental probability for rolling a 2?

Does the difference in these two probabilities mean that the die is most likely to be biased or unbiased?
