Algebra.Com's Answer #850047 by CPhill(1959)![]() ![]() You can put this solution on YOUR website! Here's how to figure out the different possible sums of dots on three adjacent faces of a standard die:\r \n" ); document.write( "\n" ); document.write( "1. **Visualize:** Imagine a die. Three adjacent faces share a common vertex (corner).\r \n" ); document.write( "\n" ); document.write( "2. **Consider the possibilities:** Since opposite faces sum to 7, the possible sets of three faces sharing a vertex are limited. Let's represent the faces by the number of dots on them.\r \n" ); document.write( "\n" ); document.write( "3. **List the combinations:** We can't have opposite faces together. Here are the distinct sets of three adjacent faces and their sums:\r \n" ); document.write( "\n" ); document.write( " * {1, 2, 3}: Sum = 6 \n" ); document.write( " * {1, 2, 4}: Sum = 7 \n" ); document.write( " * {1, 2, 5}: Sum = 8 \n" ); document.write( " * {1, 2, 6}: Sum = 9 \n" ); document.write( " * {1, 3, 4}: Sum = 8 \n" ); document.write( " * {1, 3, 5}: Sum = 9 \n" ); document.write( " * {1, 3, 6}: Sum = 10 \n" ); document.write( " * {1, 4, 5}: Sum = 10 \n" ); document.write( " * {1, 4, 6}: Sum = 11 \n" ); document.write( " * {1, 5, 6}: Sum = 12 \n" ); document.write( " * {2, 3, 4}: Sum = 9 \n" ); document.write( " * {2, 3, 5}: Sum = 10 \n" ); document.write( " * {2, 3, 6}: Sum = 11 \n" ); document.write( " * {2, 4, 5}: Sum = 11 \n" ); document.write( " * {2, 4, 6}: Sum = 12 \n" ); document.write( " * {2, 5, 6}: Sum = 13 \n" ); document.write( " * {3, 4, 5}: Sum = 12 \n" ); document.write( " * {3, 4, 6}: Sum = 13 \n" ); document.write( " * {3, 5, 6}: Sum = 14 \n" ); document.write( " * {4, 5, 6}: Sum = 15\r \n" ); document.write( "\n" ); document.write( "4. **Identify the unique sums:** The unique sums we found are 6, 7, 8, 9, 10, 11, 12, 13, 14, and 15.\r \n" ); document.write( "\n" ); document.write( "5. **Count:** There are 10 different possible sums.\r \n" ); document.write( "\n" ); document.write( "Therefore, there are 10 different sums of dots on three adjacent faces of a die. \n" ); document.write( " \n" ); document.write( " |
