问题
In a probability experiment, G and H are independent events. The probability that G will occur is r, and the probability that H will occur is s.
Quantity A: The probability that either G or H will occur, but not both
Quantity B: r+s-rs
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.
答案
D
解析
仔细进行比较,Quantity A=r+s-2rs,Quantity B=r+s-rs。在没有限制“r、s都为正数”的情况下,如果r或s取到0,Quantity A=Quantity B,因为概率的结果是[0,1],闭区间,所以在概率为零的特殊情况中,两者可能相等。这样正确答案就变成了D。
