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

To determine the experimental probability of randomly selecting a green marble from the bag, you need to know the number of times a green marble was selected out of the total number of selections.
The probability is calculated using the formula:
\[
\text{Probability (P)} = \frac{\text{Number of successful outcomes (selecting a green marble)}}{\text{Total number of trials (marble selections)}}
\]
From the options provided, you didn't include the specific details of how many green marbles were selected. If we assume from the context that the results showed that 5 out of 40 marbles selected were green, then:
\[
P(\text{green marble}) = \frac{5}{40} = 0.125
\]
However, if you have different numbers in mind, you would replace “5” with the actual count of green marbles selected.
Based on the options you provided, if we are using 5 out of 40 as an example, the experimental probability of randomly selecting a green marble would be **0.125**.
So, the correct answer in this scenario would be:
**0.125**
