摘要
本文利用全期望公式和全概公式对采取隔离措施来应对新冠肺炎疫情进行了分析,以实际问题引入较难的知识点,最终达到既解决实际问题又剖析了理论知识的目的.
The paper uses the laws of iterated expectation and total probability to analyze the isolation measures used to prevent and control COVID-19 epidemic.Difficult knowledge points are introduced by a practical problem and the necessary theories and solution to the problem are illustrated.
