1. **State the problem:** We want to find the probability that a randomly chosen person travels to school by car. 2. **Identify the total number of people and the number who travel by car:** - Total people = 30 - People traveling by car = 6 3. **Recall the formula for probability:** $$\text{Probability} = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$$ 4. **Apply the formula:** $$\text{Probability of traveling by car} = \frac{6}{30}$$ 5. **Simplify the fraction:** $$\frac{6}{30} = \frac{\cancel{6}}{\cancel{30}} = \frac{1}{5}$$ 6. **Interpretation:** The probability that a randomly chosen person travels to school by car is $\frac{1}{5}$ or 0.2.
