To find the experimental probability of randomly selecting a green marble, you can use the formula for probability:
\[
\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of trials}}
\]
From the table provided:
- Number of green marbles = 8
- Total number of selections = 40
Now, plug these values into the formula:
\[
\text{Probability of selecting a green marble} = \frac{8}{40} = \frac{1}{5} = 0.20
\]
So, the correct response is:
**0.20**
