To find the empirical probability of getting heads, we first need to determine the number of heads.
You tossed the coin 50 times and got 12 tails, so the number of heads is:
\[ \text{Number of heads} = \text{Total tosses} - \text{Number of tails} = 50 - 12 = 38 \]
Now, the empirical probability of getting heads is calculated as the number of heads divided by the total number of tosses:
\[ P(\text{heads}) = \frac{\text{Number of heads}}{\text{Total tosses}} = \frac{38}{50} \]
To express this in percentage form:
\[ P(\text{heads}) = \frac{38}{50} \times 100% \]
Calculating that:
\[ P(\text{heads}) = 0.76 \times 100% = 76% \]
So, the empirical probability of getting heads is:
\[ \boxed{76%} \]
