Algebra.Com's Answer #698422 by Boreal(15235)![]() ![]() You can put this solution on YOUR website! It can be shown that the sum is greater than 9 (10, 11, 12) is 6/36 or 1/6. Those 6 possibilities are 4-6,5-5,6-4 and 5-6, 6-5, and 6-6 \n" ); document.write( "The sum is divisible by 2: \n" ); document.write( "2: 1-1, or 1 way \n" ); document.write( "4: 1-3, 2-2-, 3-1: 3 ways \n" ); document.write( "6: 1-5, 2-4,3-3,4,2,5-1: 5 ways \n" ); document.write( "8:also 5 ways 2-6, 6-2,3-5,5-3, 4-4 \n" ); document.write( "10: 3 ways \n" ); document.write( "12: 1 way \n" ); document.write( "That is a total of 18 ways out of 36 or 1/2. \n" ); document.write( " \n" ); document.write( " |
