A number cube is rolled 120 times. The number 4 comes up 47 times. What is the experimental probability of rolling a 4? What is the theoretical probability of rolling a 4?

Question

A number cube is rolled 120 times. The number 4 comes up 47 times. What is the experimental probability of rolling a 4? What is the theoretical probability of rolling a 4?

A. Start Fraction 47 over 120 End Fraction ; start fraction 1 over 30 end fraction
B. Start Fraction 47 over 120 End Fraction ; start fraction 1 over 6 end fraction
C. Start Fraction 4 over 47 End Fraction ; start fraction 1 over 6 end fraction
D. start fraction 1 over 6 end fraction ; Start Fraction 47 over 120 End Fraction

The experimental probability of rolling a 4 is:

Start Fraction 47 over 120 End Fraction.

The theoretical probability of rolling a 4 is:

Start Fraction 1 over 6 End Fraction.

Therefore, the correct answer is B. Start Fraction 47 over 120 End Fraction ; start fraction 1 over 6 end fraction.
