求翻译：Let X be a numerically-valued discrete random varlable with sample space A and distribution function m(x).The expected value E(X) is denfined by E(X) provided this sum converges absolutely.We often refer to the expected value as the mean,and denote E(X) by u for short.If the above sum does not converge absolutely, then是什么意思？ 待解决

让X是数控价值离散随机varlable与样本一和空间分布函数M(x).的预期价值E(x)是由denfined E(x)提供了这笔款项承接绝对.我们经常提到,预期的价值的意思,是指E(x)由u作短期.如果上述款项绝对不衔接,然后我们说X没有一个预期值。

让 X 是数字值离散随机变量分布函数 m(x) 与样本空间 A。E(X) 是由 E(X) denfined 提供这笔预期值绝对收敛。我们经常引用预期值的平均数，并由短的 u 表示 E(X)。如果上述款项未绝对收敛，我们说 X 没有一个预期的值。
