**Probability Exercise: Calculating Probabilities with Replacement**

**Scenario:**
There are 10 red balls and 10 yellow balls mixed in a drum. What is the probability of drawing a red ball on the first try, replacing it in the drum, and then drawing a yellow ball on the second try?

**Instructions:**
Choose from the formulas below and then calculate the probability for the given scenario. Round your final answer to two decimal places.

**Formulas:**
1. **Formula 1:** 
   - \( p(A) = \frac{\text{Number of events classifiable as A}}{\text{Total number of possible events}} \)

2. **Formula 2:** 
   - \( p(A \text{ or } B) = p(A) + p(B) \)

3. **Formula 3:** 
   - \( p(A \text{ and } B) = p(A) \times p(B|A) \)

4. **Formula 4:** 
   - \( p(A \text{ and } B) = p(A) \times p(B) \)

5. **Formula 5:** 
   - No formula provided

**Answer:**
Use the appropriate formula to calculate the probability of the given scenario and input your result in the provided answer box.
