7: (1,6),(6,1),(2,5),(5,2),(3,4),(4,3)⇒(6/(36))=(1/6)
$$\mathrm{7}:\:\left(\mathrm{1},\mathrm{6}\right),\left(\mathrm{6},\mathrm{1}\right),\left(\mathrm{2},\mathrm{5}\right),\left(\mathrm{5},\mathrm{2}\right),\left(\mathrm{3},\mathrm{4}\right),\left(\mathrm{4},\mathrm{3}\right)\Rightarrow\frac{\mathrm{6}}{\mathrm{36}}=\frac{\mathrm{1}}{\mathrm{6}}\: \\ $$
