独立重复试验是在相同条件下进行的只有对立事件A与的n次独立试验,从计算的角度来看,在解答过程中蕴涵了丰富的四则运算中的“加、减、乘”规律.下面就“加、减、乘”的策略在处理独立重复试验的概率计算中的应用结合例题予以分析. The independent repetitive tests are n independent experiments with opposite events A and 在 conducted under the same conditions. From the point of view of calculation, the “plus, subtract, multiply” rules in the four arithmetic operations are contained in the solution process. The following analysis of the application of the “add, subtract, multiply” strategy in dealing with probability calculations of independent repetitive tests is combined with examples.
