A geometric solid with 8 faces is used in a game. Each face of the solid is labeled with a different number from 1 to 8. Amelia rolled the solid 30 times and recorded the number showing on the top face. The results are shown in the table.
8. 8. 2. 5. 4. 6. 1. 3. 8. 2. 7. 8. 2. 3. 1. 8. 1. 1. 5. 7. 8. 3. 3. 1. 1. 6. 1. 4. 3. 8.
Based on these results, what is the experimental probability that the next time the solid is rolled, it will land with a 7 showing on the top face?
To find the experimental probability of rolling a 7, we count the number of times a 7 appeared on the top face of the solid in the results:
Number of 7's rolled: 2
Experimental probability of rolling a 7 = Number of successful outcomes / Total number of outcomes
Experimental probability of rolling a 7 = 2 / 30
Experimental probability of rolling a 7 = 1/15
Therefore, based on the results, the experimental probability of rolling a 7 on the next roll is 1/15.
