Dear student

defender – {1,2,3,4,5,6}
attacher – { 1, {1,2,3,4,5,6} }, { 2, {1,2,3,4,5,6} }, { 3, {1,2,3,4,5,6} }, { 4, {1,2,3,4,5,6} }, { 5,{1,2,3,4,5,6} }, { 6, {1,2,3,4,5,6} };

for 1 of defender – 6+6+6+6+6+6 ways;
for 2 of defender – 5+6+6+6+6+6 ways;
for 3 of defender – 4+4+6+6+6+6 ways;
for 4 of defender – 3+3+3+6+6+6 ways;
for 5 of defender – 2+2+2+2+6+6 ways;
for 6 of defender – 1+1+1+1+1+6 ways;

Probability (attacker winning ) = (36+35+32+27+20+11) ./ (36*6)
