当前互联网上广为流传的关于“划拳”问题的概率计算,是站在独立第三方的立场上给出的解答,结论是不符合实际的.本文将站在划拳参与者的立场上,以划拳中甲乙双方的甲方为例,在甲出拳赢拳的策略原则下,通过使用古典概型枚举分析的方法、独立和互斥事件的概率计算、条件概率的计算,用三种方法计算和验证“划拳”中的概率问题.首先,我们用古典概型和枚举分析的方法进行计算,具体计算过程如下:划拳时,用手势表示不同的数:拳头表示0,1
The current widespread on the Internet on the “stroke boxing ” probability calculation is based on the standpoint of an independent third party given the answer, the conclusion is not realistic.This article will stand in the position of boxing participants, Taking the case of Party A of Party A and Party B in boxing as an example, under the strategic principle of winning a boxing punch through the use of classical enumeration analysis method, the probability calculation of independent and mutually exclusive events, the conditional probability calculation, Method to calculate and verify the probability problem in “stroke boxing.” First of all, we use classical method and enumeration method to calculate. The specific calculation process is as follows: When stroke, different gestures are used to express different numbers:
