To calculate the experimental probability of getting heads in your coin flips, you first need to count the number of heads (H) and the total number of flips.

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

1. Count the number of heads (H):
- There are 8 heads in total.

2. Count the total number of flips:
- The total number of flips is 20.

3. Now, use the formula for experimental probability:
\[
\text{Experimental Probability of Heads} = \frac{\text{Number of Heads}}{\text{Total Number of Flips}} = \frac{8}{20}
\]

4. To express this as a percent:
\[
\frac{8}{20} = 0.4
\]

\[
0.4 \times 100 = 40\%
\]

So, the experimental probability of getting heads is **40%**.
