标题： Clebsch-Gordan coefficients and the binomial distribution

摘要： 一类Clebsch-Gordan系数由条件概率的性质通过二项分布导出。 特别是，在$l=l_1+l_2$的情况下，证明了$$[<l_1/2-k_1, l_2/2-k_2|l/2, k=k_1+k_2]>^2 =\frac{(\begin{array}{c} l_1 k_1\end{array} ) (\begin{array}{c}l_2 k_2\end{array} )}{(\begin{array}{c}l k \end{array} )}$$ 显示英文摘要

摘要： A class of Clebsch-Gordan coefficients are derived from the properties of conditional probability using the binomial distribution. In particular, in the case of $l=l_1+l_2$ it is shown that $$[<l_1/2-k_1, l_2/2-k_2|l/2, k=k_1+k_2]>^2 =\frac{(\begin{array}{c} l_1 k_1\end{array}) (\begin{array}{c}l_2 k_2\end{array})}{(\begin{array}{c}l k \end{array})}$$
