To calculate the experimental probability of rolling a 1 based on the results of the experiment, you use the formula:
\[ \text{Experimental Probability} = \frac{\text{Frequency of the outcome}}{\text{Total number of trials}} \]
From the table, the frequency of rolling a 1 is 245, and the total number of rolls is 1,230.
Now, plug in the numbers:
\[ \text{Experimental Probability of rolling a 1} = \frac{245}{1230} \]
Calculating this gives:
\[ \frac{245}{1230} \approx 0.1992 \]
Thus, the experimental probability of rolling a 1 on your next roll is approximately 0.1992.
