To calculate the experimental probability of rolling a 1, you need to know how many times a 1 was rolled during the experiment compared to the total number of rolls. The experimental probability is calculated using the formula:
\[ \text{Experimental Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}} \]
From the information you provided, you mentioned that the die was rolled 1,230 times. However, the specific count of how many times a 1 was rolled is missing from your message.
Assuming you have the count (let's say \( n \) is the number of times a 1 was rolled), you would calculate the experimental probability of rolling a 1 as follows:
\[ \text{Experimental Probability of rolling a 1} = \frac{n}{1230} \]
Please provide the number of times a 1 was rolled for a specific calculation.
