To find the likelihood of picking a green marble from the box, we first need to determine the total number of marbles and then the number of green marbles.
- Number of red marbles: 4
- Number of green marbles: 5
- Number of blue marbles: 3
Total number of marbles = 4 (red) + 5 (green) + 3 (blue) = 12 marbles.
Now, the number of green marbles is 5.
The probability of picking a green marble is calculated as:
\[
\text{Probability of green marble} = \frac{\text{Number of green marbles}}{\text{Total number of marbles}} = \frac{5}{12}
\]
Since there is a positive chance (5 out of 12) of picking a green marble, it is neither impossible nor certain. Evaluating the likelihood:
- "Likely" suggests a probability greater than 0.5.
- "Impossible" means the event cannot happen at all.
- "Certain" means the event will definitely happen (probability of 1).
- "Equally Likely" would mean all outcomes have the same probability.
- "Unlikely" suggests a probability less than 0.5 but greater than 0.
Since the probability of picking a green marble (5/12) is less than 0.5, it can be categorized as "Unlikely."
Thus, the answer is:
**E. Unlikely**
- Number of red marbles: 4
- Number of green marbles: 5
- Number of blue marbles: 3
Total number of marbles = 4 (red) + 5 (green) + 3 (blue) = 12 marbles.
Now, the number of green marbles is 5.
The probability of picking a green marble is calculated as:
\[
\text{Probability of green marble} = \frac{\text{Number of green marbles}}{\text{Total number of marbles}} = \frac{5}{12}
