1. **State the problem:** We want to find the experimental probability that a randomly selected vehicle is not blue. 2. **Recall the formula for experimental probability:** $$P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$$ 3. **Identify the total number of vehicles:** Total vehicles = 7171 4. **Identify the number of blue vehicles:** Blue vehicles = 33 5. **Calculate the number of vehicles that are not blue:** $$\text{Not blue} = 7171 - 33 = 7138$$ 6. **Calculate the probability that a vehicle is not blue:** $$P(\text{not blue}) = \frac{7138}{7171}$$ 7. **Simplify or approximate the probability:** $$P(\text{not blue}) \approx 0.9954$$ **Final answer:** $$P(\text{not blue}) = \frac{7138}{7171} \approx 0.9954$$
