all the money =1  1−(5/(11))−(7/(12))×(1−(5/(11)))=(6/(11))−(7/(12))×(6/(11))=(6/(11))−(7/(22))=(5/(22))
$$\mathrm{all}\:\mathrm{the}\:\mathrm{money}\:=\mathrm{1} \\ $$$$\mathrm{1}−\frac{\mathrm{5}}{\mathrm{11}}−\frac{\mathrm{7}}{\mathrm{12}}×\left(\mathrm{1}−\frac{\mathrm{5}}{\mathrm{11}}\right)=\frac{\mathrm{6}}{\mathrm{11}}−\frac{\mathrm{7}}{\mathrm{12}}×\frac{\mathrm{6}}{\mathrm{11}}=\frac{\mathrm{6}}{\mathrm{11}}−\frac{\mathrm{7}}{\mathrm{22}}=\frac{\mathrm{5}}{\mathrm{22}} \\ $$
