To calculate the experimental probability of rolling a 2, you can use the formula for experimental probability:
\[ \text{Experimental Probability} = \frac{\text{Frequency of the outcome}}{\text{Total number of trials}} \]
From the data provided:
- Frequency of rolling a 2 = 172
- Total number of rolls = 1230
Now substitute these values into the formula:
\[ \text{Experimental Probability of rolling a 2} = \frac{172}{1230} \]
Calculating that gives:
\[ \frac{172}{1230} \approx 0.13984 \]
To convert this to a percentage, multiply by 100:
\[ 0.13984 \times 100 \approx 13.98% \]
So, the experimental probability of rolling a 2 on your next roll is 13.98%.
