The table shows the results of randomly selecting a colored marbled from a bag 40 times. The marble was returned to the bag after each selection.

purple: 16
green:8
blue:6
white:9
pink:1

Based on these results, what is the experimental probability of randomly selecting a green marble from the bag in one attempt?

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
