The ChiSquare1D.php class needs access to the Chi Square methods in Distribution.php to compute the tail probability of an obtained Chi Square value.

php 类必须能够访问 Distribution.php 中的 X 平方分布方法，以计算所得到的 X 平方分布值的尾数概率。

The obtained Chi Square value is re-expressed as a tail probability value -- in this case, 0.02.

获得的 X 平方分布值被重新表示成尾数概率值 — 在本例中是 0.02。

In practice, I don't use such graphs to compute tail probabilities because I can implement mathematical functions to return the tail probability for a given Chi Square value.

实际上，我不使用这些图来计算尾数概率，因为我可以实现数学函数来返回给定x平方分布值的尾数概率。

Shane Watson went for 20 in the penultimate over of the innings as he lost his line and length and bowled a series of wide full tosses that the Indian tail-enders merrily smeared through the covers and behind square.
