The problem in the image can be broken down and solved as follows:

**Problem:**
In a box, there are:
- 4 red marbles,
- 5 green marbles,
- 3 blue marbles.

A marble is drawn randomly. Determine the probability of drawing:
1. A blue marble.
2. A green marble.

### Solution:

1. **Total number of marbles**:
   \[
   4 (\text{red}) + 5 (\text{green}) + 3 (\text{blue}) = 12 \text{ marbles in total}.
   \]

2. **Probability of drawing a blue marble**:
   The number of blue marbles is 3. Therefore, the probability of drawing a blue marble is:
   \[
   P(\text{blue}) = \frac{3}{12} = \frac{1}{4}.
   \]

3. **Probability of drawing a green marble**:
   The number of green marbles is 5. Therefore, the probability of drawing a green marble is:
   \[
   P(\text{green}) = \frac{5}{12}.
   \]

### Final Answers:
1. The probability of drawing a blue marble is \(\frac{1}{4}\).
2. The probability of drawing a green marble is \(\frac{5}{12}\).
