What is the best explanation of how to find the experimental probability of rolling a 3?
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.
the answer is 9/60
To find the experimental probability of rolling a 3, you need to determine the frequency of rolling a 3 compared to the total number of trials.
In this case, the table provides the frequencies of each number rolled. The frequency for rolling a 3 is given as 5.
To find the experimental probability of rolling a 3, divide the frequency of rolling a 3 by the total number of trials. The total number of trials is the sum of all the frequencies, which in this case is 4 + 6 + 5 + 7 + 3 + 5 = 30.
So, the experimental probability of rolling a 3 is calculated as 5/30.
Therefore, the best explanation of how to find the experimental probability of rolling a 3 is to divide the frequency of rolling a 3 by the total number of trials.
