\[10 + 9 + 6 = 25.\]
\[\textbf{а)}\ \frac{6}{25} \cdot \frac{5}{24} \cdot \frac{10}{23} = \frac{1 \cdot 1 \cdot 5}{5 \cdot 2 \cdot 23} = \frac{1}{46}.\]
\[\textbf{б)}\ \frac{9}{25} \cdot \frac{8}{24} \cdot \frac{10}{23} = \frac{3 \cdot 1 \cdot 2}{5 \cdot 1 \cdot 23} = \frac{6}{115}.\]
\[\textbf{в)}\ \frac{6}{25} \cdot \frac{10}{24} \cdot \frac{9}{23} = \frac{1 \cdot 1 \cdot 9}{5 \cdot 2 \cdot 23} = \frac{9}{230}.\]
\[\textbf{г)}\ \frac{10}{25} \cdot \frac{9}{24} \cdot \frac{8}{23} = \frac{2}{5} \cdot \frac{3}{8} \cdot \frac{8}{23} = \frac{6}{115}.\]
