1. **State the problem:** Find the experimental probability of getting a 0 or 5 from the lottery machine data. 2. **Formula:** Experimental probability = \frac{Number\ of\ times\ event\ occurred}{Total\ trials} 3. **Given data:** Number of times 0 appeared = 20, Number of times 5 appeared = 25, Total trials = 200 4. **Calculate experimental probability:** $$\text{Experimental probability} = \frac{20 + 25}{200} = \frac{45}{200}$$ 5. **Simplify the fraction:** $$\frac{45}{200} = \frac{\cancel{5}9}{\cancel{5}40} = \frac{9}{40} = 0.225$$ 6. **Interpretation:** The experimental probability of getting a 0 or 5 is 0.225, meaning in the 200 trials, about 22.5% of the outcomes were either 0 or 5.
