Algebra.Com's Answer #378337 by jim_thompson5910(35256)![]() ![]() ![]() You can put this solution on YOUR website! If you have 7 selections, and 6 of them are taken up by apples, then the last selection must be an orange.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "There are 8 apples. So there are 8 C 6 = (8!)/(6!(8-6)!) = 28 ways to select 6 apples (from 8)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "There are 6 oranges. Since the there's only one spot for an orange, there are only 6 ways to select an orange.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "So multiply these results to get 28*6 = 168\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "This means that there are 168 ways to select exactly 6 apples. \n" ); document.write( " |
