Question

A number cube was rolled as part of an experiment. The results are in the table below. The fraction 1/x is the experimental probability of rolling a 3. What is x?

Experiment Results
Number 1 2 3 4 5 6

Frequency 4 6 5 7 3 5

Answer 1

its d

Explanation:

Answer 2

Answer: x is 6

Explanation:

The probability of rolling a 6 on a 6-sided cube is 1/6

In the experiment the frequencies of all the numbers added up to 30

The frequency of the number 3 turned out to be 5. 5 out of 30 is also 1/6. (Nice coincidence.)
