题目
q represents a probability value and q is different from zero
选项
C.The two quantities are equal.
D.The relationship cannot be determined from the information given.
解析
答案是D。
概率值始终介于0(不可能事件)和1(必然事件)之间。
设 q = 0.1 → q × (1 - q) = 0.1 × 0.9 = 0.09,该值小于0.1
设 q = 0.2 → q × (1 - q) = 0.2 × 0.8 = 0.16,该值大于0.1
因此,两者的大小关系无法确定。
