A number cube was rolled as part of an experiment. The results are displayed in the table below. Number 1 2 3 4 5 6 Frequency 4
6 5 7 3 5 What is the best explanation of how to find the experimental probability of rolling a 3? A) To find the experimental probability of rolling a three, write a ratio of the number of times three occurs to the total number of trials. Simplify if necessary.
B) To find the experimental probability of rolling a three, write a ratio of the total number of trials to the frequency of the number three. Simplify if necessary.
C) To find the experimental probability of rolling a three, write a ratio of the number three to the total number of trials. Simplify if necessary.
D) To find the experimental probability of rolling a three, write a ratio of the total number of trials to the number three. Simplify if necessary.
Sample Response/Explanation: To find the experimental probability, compare the total number of times the event occurs to the total number of trials. Compare the frequency of rolling the number six (9) to the total number of trials (60) using a ratio, and then reduce.
