1. **With Replacement:**
- Calculate the probability of drawing a king each time with replacement.
- Each time, the probability of a king is \frac{4}{52} .
- Thus, the combined probability for three draws is:
\left( \frac{4}{52} \right) \times \left( \frac{4}{52} \right) \times \left( \frac{4}{52} \right) = \left( \frac{1}{13} \right)^3 = \frac{1}{2197} .

2. **Without Replacement:**
- Calculate the probability of drawing a king each time without replacement.
- First draw: \frac{4}{52} .
- Second draw: \frac{3}{51} since one king is gone.
- Third draw: \frac{2}{50} since two kings are gone.
- Thus, the combined probability for three draws is:
\frac{4}{52} \times \frac{3}{51} \times \frac{2}{50} = \frac{24}{132600} = \frac{1}{5525} .

3. **Answer:**
- Probability with replacement: \frac{1}{2197}
- Probability without replacement: \frac{1}{5525}
