Quantity B: the probability that events R will not occur 0.52
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 事件R和W同时发生的概率是0.48。如果两者为独立事件，那么两者同时发生的概率必然小于单个事件发生的概率，事件R发生的最小概率为0.48，那么事件R不发生的最大概率为0.52。选择D。
