For instance, the '8' in row 3, column 5 is found by adding 3 and 5. So 3+5 = 8. The other cells are found this way.\r \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "You can see that there are 4 copies of '5' and 2 copies of '11'. So there are 4+2 = 6 copies of what we want (which is either 5 or 11). \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "This is out of 6*6 = 36 possible outcomes. \r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So the answer as a fraction is |
