### Probability Question on Compound Events

**Question 10**

Given the following probabilities:
- \( P(C) = 0.2 \)
- \( P(D) = 0.3 \)
- \( P(C \mid D) = 0.4 \),

we need to calculate \( P(C \text{ and } D) \).

Choose the correct answer from the following options:

1. \( 0.06 \)
2. \( 0.08 \)
3. \( 0.1 \)
4. \( 0.12 \)
5. \( 0.5 \)
6. \( 0.9 \)
7. \( 0 \)
8. \( 1 \)

Using the formula for conditional probability:
\[ P(C \mid D) = \frac{P(C \text{ and } D)}{P(D)} \]

we can solve for \( P(C \text{ and } D) \):
\[ P(C \text{ and } D) = P(C \mid D) \times P(D) \]

Plugging in the given values:
\[ P(C \text{ and } D) = 0.4 \times 0.3 = 0.12 \]

Thus, the correct answer is:

4. \( 0.12 \)
