1. **State the problem:** We have a spinner divided into 5 equal sectors: Red, Blue, Yellow, Blue, Yellow. 2. **Formula for probability:** The probability of landing on a particular color is given by $$\text{Probability} = \frac{\text{Number of sectors of that color}}{\text{Total number of sectors}}$$ 3. **Calculate probability for red:** There is 1 red sector out of 5 total sectors. $$\text{Probability of red} = \frac{1}{5}$$ 4. **Calculate probability for yellow:** There are 2 yellow sectors out of 5 total sectors. $$\text{Probability of yellow} = \frac{2}{5}$$ 5. **Explanation:** Since all sectors are equal in size and the spinner cannot land on a line, the probability is simply the fraction of sectors of the desired color over the total sectors. **Final answers:** - Probability of landing on red: $\frac{1}{5}$ - Probability of landing on yellow: $\frac{2}{5}$
