The experimental probability of an event is calculated as the number of successful outcomes divided by the total number of trials.
In this scenario:
- The number of successful outcomes (heads) is 7.
- The total number of trials (coin tosses) is 12.
Thus, the experimental probability \( P \) of getting heads is calculated as follows:
\[
P(\text{heads}) = \frac{\text{Number of heads}}{\text{Total number of tosses}} = \frac{7}{12}
\]
So, the correct answer is \( \frac{7}{12} \).
In this scenario:
- The number of successful outcomes (heads) is 7.
- The total number of trials (coin tosses) is 12.
Thus, the experimental probability \( P \) of getting heads is calculated as follows:
\[
P(\text{heads}) = \frac{\text{Number of heads}}{\text{Total number of tosses}} = \frac{7}{12}
\]
So, the correct answer is \( \frac{7}{12} \).
