you are wrong the correct method is possible ways (25,0);(22,2);(19,4);(16,6);(13,8);(10,10);(7,12);(4,14);(1,16) now we have to permute each case to get the result (25!)/(25!)+(24)!/(22!2!)+(23!)/(19!4!)+(22!)/(16!6!)+(21!)/(13!8!)+(20!)/(10!)(10!)+(19!)/(7!12)!+(18!)/(14!4!)+(17!)/(16!) calculate this and you will get the result thank you.........
