Answer 1

To find the experimental probability of getting heads when flipping a coin, you need to follow these steps:

1. Count the number of heads in the results.
2. Count the total number of flips.
3. Use the formula for experimental probability:

\[
\text{Experimental Probability of Heads} = \frac{\text{Number of Heads}}{\text{Total Flips}}
\]

**Counting the results**:

From the results you provided:
- H H T T T H T T H T H H T T T H

Count the "H" outcomes:
- Heads (H): 7
- Total Flips: 16

Now we can calculate the experimental probability:

\[
\text{Experimental Probability of Heads} = \frac{7}{16}
\]

Now, convert this fraction to a percentage:

\[
\frac{7}{16} \approx 0.4375 \text{ (when calculated as a decimal)}
\]

To convert to a percentage, multiply by 100:

\[
0.4375 \times 100 = 43.75\%
\]

Rounding this to the nearest percent gives us:

\[
44\%
\]

Therefore, the experimental probability of getting heads is **44%**.
