1. **State the problem:** We want to estimate the probability of Edward winning the prize wheel after 800 spins, given previous data. 2. **Given data:** - Total spins so far: 700 - Edward's wins so far: 0.42 * 700 = 294 (since 0.42 is the probability of winning per spin) - Total spins after additional spins: 700 + 100 = 800 - Edward's wins after additional spins: 58 3. **Calculate total wins after 800 spins:** $$\text{Total wins} = 294 + 58 = 352$$ 4. **Calculate estimated probability of winning after 800 spins:** $$P = \frac{\text{Total wins}}{\text{Total spins}} = \frac{352}{800} = 0.44$$ 5. **Interpretation:** The estimated probability of Edward winning after 800 spins is **0.44** or 44%.
