独立事件同时发生的概率不是相乘吗

问题如下：

Which of the following is a property of two dependent events?

选项：

The two events must occur simultaneously.

The probability of one event influences the probability of the other event.

The probability of the two events occurring is the product of each event’s probability.

解释：

B is correct.

The probability of the occurrence of one is related to the occurrence of the other. If we are trying to forecast one event, information about a dependent event may be useful.

一种发生的概率与另一种发生的概率有关。 如果我们去预测一个事件，那么有关相关事件的信息可能很有用。
