Algebra.Com's Answer #710904 by greenestamps(13198)![]() ![]() You can put this solution on YOUR website! If the red die shows 1, then any of the 6 numbers on the green die will make a sum of less than 9: \n" ); document.write( "R,G = 1,1 or 1,2 or 1,3 or 1,4 or 1,5 or 1,6 --> 6 ways \n" ); document.write( "If the red die shows 2, then still any of the 6 numbers on the green die will make a sum of less than 9: \n" ); document.write( "R,G = 2,1 or 2,2 or 2,3 or 2,4 or 2,5 or 2,6 --> 6 ways \n" ); document.write( "If the red die shows 3, then now only 5 of the 6 numbers on the green die will make a sum of less than 9: \n" ); document.write( "R,G = 3,1 or 3,2 or 3,3 or 3,4 or 3,5 --> 5 ways \n" ); document.write( "If the red die shows 4, then now only 4 of the 6 numbers on the green die will make a sum of less than 9: \n" ); document.write( "R,G = 4,1 or 4,2 or 4,3 or 4,4 --> 4 ways \n" ); document.write( "If the red die shows 5, then now only 3 of the 6 numbers on the green die will make a sum of less than 9: \n" ); document.write( "R,G = 5,1 or 5,2 or 5,3 --> 3 ways \n" ); document.write( "And if the red die shows 6, then now only 2 of the 6 numbers on the green die will make a sum of less than 9: \n" ); document.write( "R,G = 6,1 or 6,2 --> 2 ways \n" ); document.write( "The total number of ways to get a sum less than 9 is \n" ); document.write( "6+6+5+4+3+2 = 26\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
