被4整除特征，后两位是4的倍数 .
$\begin{matrix} 00 \\ \checkmark \end{matrix}, 02, \begin{matrix} 04 \\ \checkmark \end{matrix}, 06, \begin{matrix} 08 \\ \checkmark \end{matrix} \quad \text{每组情况一致、为} \ \frac{3}{5} .$
$\begin{matrix} 20 \\ \checkmark \end{matrix}, 22, \begin{matrix} 24 \\ \checkmark \end{matrix}, 26, \begin{matrix} 28 \\ \checkmark \end{matrix}$
$1 - \frac{3}{5} = \frac{2}{5} .$
