A number cube was rolled as part of an experiment. The results are shown in the table. Explain how to find the experimental probability of rolling a 6.
that not it
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.
ok cool
To find the experimental probability of rolling a 6 with a number cube, you need to know the total number of times a 6 was rolled and the total number of rolls conducted. Here's how you can calculate it:
1. Look at the table that shows the results of the number cube rolls. Locate the column or row that represents the number 6 since you're interested in finding the probability of rolling a 6.
2. Identify the total number of times a 6 was rolled. This number should be specified in the table. Let's assume it is 8 times.
3. Determine the total number of rolls conducted in the experiment. This information may be mentioned in the table or provided separately. For example, if the experiment involved rolling the number cube 40 times, this would be the total number of rolls.
4. Divide the number of times a 6 was rolled by the total number of rolls to find the experimental probability. In this case, divide 8 by 40. The result is 0.2.
Therefore, the experimental probability of rolling a 6 with the number cube is 0.2 or 20%.
