1. **Problem:** A bowl contains 10 chips numbered 1 to 10. Find the probability of drawing a chip with certain properties. 2. **Formula:** Probability of an event $E$ is given by $$P(E) = \frac{\text{Number of favorable outcomes}}{\text{Total number of outcomes}}$$ 3. **Important rules:** - Total outcomes = 10 (chips numbered 1 to 10). - We count favorable outcomes based on the condition. 4. **Part (a): Probability of drawing 7 or 10** - Favorable outcomes: {7, 10} - Number of favorable outcomes = 2 - $$P(7 \text{ or } 10) = \frac{2}{10}$$ - Simplify fraction: $$P = \frac{\cancel{2}}{\cancel{10}} = \frac{1}{5}$$ **Final answer:** $\boxed{\frac{1}{5}}$ This completes the solution for the first question.
