Probability is an important content of high school mathematics, and it is also a focus and hotspot of the college entrance examination in recent years. It has a tendency of rising year by year. From the examination questions in recent years, we mainly examine the probability of random events, possible events, mutually exclusive events, and opposition events. Independent events.
