q represents a probability value and q is different from zero


Quantity A

[q][1-q]

Quantity B

0.1

选项

A.

Quantity A is greater.


B.

Quantity B is greater.


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。
