A special 8-sided die is marked with the numbers 1 to 8. It is rolled 20 times with these outcomes: 3 4 5 2 7 1 3 7 2 6 2 1 7 3 6 1 8 3 5 6 The experimental probability of rolling a prime number is %, which is % more than the theoretical probability.
Accepted Solution
A:
the prime numbers on the dice are 1,2,3,5 and 7 , the theoretical probability is [tex] \frac{5}{8} [/tex], which is 62.5%, the number of prime numbers in the outcome is 15, so the experimental probability is [tex] \frac{3}{4} [/tex], which is 75%, the difference between the experimental probability and the theoretical probability is 12.5%.
