A number cube was rolled as part of an experiment. The results are shown in the table.
number: 1 2 3 4 5 6
frequency: 13 11 9 8 10 9
Explain how to find the experimental probability of rolling a 6.
9 rolls were 6
total rolls were 60
So, P(6) = 6/60
To find the experimental probability of rolling a 6, you need to determine the number of times a 6 was rolled and divide it by the total number of rolls. In this case, the frequency table provides the information you need. Here's how you can find the experimental probability:
1. Look at the frequency of the number 6 in the table. In this case, the frequency for 6 is 9.
2. Add up all the frequencies in the table to find the total number of rolls. In this case, the sum of all the frequencies is 13 + 11 + 9 + 8 + 10 + 9 = 60.
3. Divide the frequency of 6 by the total number of rolls. So, 9 / 60 = 0.15.
Therefore, the experimental probability of rolling a 6 is 0.15, which can also be expressed as 15%.
