某校为开展“阳光体育”活动，组织调查了该校50名学生各自最喜爱的一项体育活动，制成了扇形统计图，其中篮球占10%，跑步占30%，其他占20%，全校共有3000名学生，估计该学校选择篮球的学生有多少名？---**Chart Description:** * **Type:** Pie chart. * **Main Elements:** The chart is a circle divided into four sectors. Each sector represents a different category of activity and is labeled with the activity name and a percentage. * One sector is labeled "篮球" (Basketball) and "10%". * One sector is labeled "羽毛球" (Badminton). The percentage for this sector is not explicitly written, but can be inferred. * One sector is labeled "跑步" (Running) and "30%". * One sector is labeled "其他" (Other) and "20%". * **Inferred Data:** The total percentage for all categories in a pie chart must be 100%. The sum of the known percentages is 10% (Basketball) + 30% (Running) + 20% (Other) = 60%. Therefore, the percentage for "羽毛球" (Badminton) is 100% - 60% = 40%. **Extracted Textual Information:** * 篮球: 10% * 羽毛球 * 跑步: 30% * 其他: 20%
