1. The problem asks us to analyze a circle graph (pie chart) showing students' favorite colors: Blue, Red, Pink, Other, Green, and Purple. 2. (a) We need to find which color was chosen by approximately one-third of the students. Since one-third is about 33.3%, we look for the sector that covers roughly one-third of the circle. 3. (b) We need to find the approximate percentage of students who chose Pink or Purple combined. We will estimate the sum of the sectors for Pink and Purple. 4. Since the exact sector sizes are not given numerically, we rely on the visual approximation from the pie chart. 5. (a) The sector labeled Blue appears to cover about one-third of the circle, so Blue is the color chosen by approximately one-third of the students. 6. (b) The sectors for Pink and Purple together appear to cover about 30% of the circle. 7. Therefore, the answer to (a) is Blue. 8. The answer to (b) is approximately 30%.
