krok68 [10]

Answer:

Here both probabilities are not equal.

Therefore the die is not fair and biased.

Step-by-step explanation:

Now n= 1200 times and x = 419 times.

a) Empirical Probability:

         =\frac{x}{n} \\\\= \frac{419}{1200}\\ \\=0.349

Probability = 0.349

b) Theoretical Probability:

                     =\frac{1}{6}

Here both probabilities are not equal.

Therefore the die is not fair and biased.
