### Example Problem:
*Problem*: Solve for \( x \) in the equation \( 2x + 3 = 11 \).

### Expected Format:
*Step 1*: Subtract 3 from both sides of the equation.  
<thinking>Subtracting 3 from both sides should isolate the term with \( x \). Am I confident this is the correct first step? Yes, because it simplifies the equation to \( 2x = 8 \).</thinking>  
*Step 1 Confidence Score*: 0.85

*Step 2*: Divide both sides by 2.  
<thinking>Dividing by 2 will solve for \( x \). This is a straightforward division. Is there any reason to doubt this step? No, it should give \( x = 4 \).</thinking>  
*Step 2 Confidence Score*: 0.90

*Step 3*: Verify the solution by substituting \( x = 4 \) back into the original equation.  
<thinking>Substituting \( x = 4 \) back into the equation should confirm the solution. Does \( 2(4) + 3 = 11 \)? Yes, it does, so the solution is verified.</thinking>  
*Step 3 Confidence Score*: 1.00

Question: A bag contains 5 red marbles, 3 blue marbles, and 2 green marbles. If two marbles are drawn at random without replacement, what is the probability that one is blue and the other is not red? Express your answer as a common fraction.
Answer: Let's analyze the problem step by step.

1. The total number of marbles in the bag is:
\[ 5 \text{ red} + 3 \text{ blue} + 2 \text{ green} = 10 \text{ marbles} \]

2. We want to find the probability that one marble is blue and the other is not red. There are two ways this can happen:
   - The first marble drawn is blue, and the second is not red.
   - The first marble drawn is not red, and the second is blue.

3. Probability of the first marble being blue:
\[ P(\text{blue}) = \frac{3 \text{ blue}}{10 \text{ total}} = \frac{3}{10} \]

4. If the first marble is blue, the probability that the second marble is not red (given that the first was blue):
   - There are now 9 marbles left, of which 5 are red and 4 are not red (2 green and 2 blue since one blue has been removed).
   - The probability of the second marble not being red is:
   \[ P(\text{not red}|\text{first blue}) = \frac{4 \text{ not red}}{9 \text{ total remaining}} = \frac{4}{9} \]

5. The combined probability for this sequence (blue then not red) is:
   \[ P(\text{blue then not red}) = P(\text{blue}) \times P(\text{not red}|\text{first blue}) = \frac{3}{10} \times \frac{4}{9} = \frac{12}{90} \]

6. Now, let's consider the probability of the first marble being not red:
   \[ P(\text{not red}) = \frac{5 \text{ not red}}{10 \text{ total}} = \frac{5}{10} = \frac{1}{2} \]

7. If the first marble is not red, the probability that the second marble is blue (given that the first was not red):
   - There are now 9 marbles left. The number of blue marbles remains 3 (since the first marble was not red, and we don't know which color was picked first).
   - The probability of the second marble being blue is:
   \[ P(\text{blue}|\text{first not red}) = \frac{3 \text{ blue}}{9 \text{ total remaining}} = \frac{3}{9} = \frac{1}{3} \]

8. The combined probability for this sequence (not red then blue) is:
   \[ P(\text{not red then blue}) = P(\text{not red}) \times P(\text{blue}|\text{first not red}) = \frac{1}{2} \times \frac{1}{3} = \frac{1}{6} \]

9. Since these two scenarios are mutually exclusive (they cannot happen at the same time), we add their probabilities together to find the total probability of one marble being blue and the other not red:
   \[ P(\text{blue and not red}) = P(\text{blue then not red}) + P(\text{not red then blue}) = \frac{12}{90} + \frac{1}{6} \]
   \[ P(\text{blue and not red}) = \frac{12}{90} + \frac{15}{90} = \frac{27}{90} = \frac{3}{10} \]

Thus, the probability that one marble is blue and the other is not red is $\frac{3}{10}$.

The final answer is: $\boxed{\frac{3}{10}}$
