一道GRE数学题，求大神解答

In a survey of students, each student selected from a list of 12 songs the 2 songs that the student liked best. If each song was selected 4 times, how many students were surveyed?

Answer 1

答案错了吧，三角形面积 π*（半径）/2，扇形面积 π*（半径）平方/6，π/6 > 1/2 ,应该是扇形面积大
满意请采纳。

Answer 2

一群学生， 每人从12首歌的列表中选出2首最喜欢的， 如果每首歌被选择了4次， 学生应该有多少人？

12X4=48（次） 每人选2首， 共计48/2=24（人）
