The combination formula is:\r
\n" ); document.write( "\n" ); document.write( "C(n, r) = n! / (r! * (n-r)!)\r
\n" ); document.write( "\n" ); document.write( "Where n is the total r is the number we choose. \r
\n" ); document.write( "\n" ); document.write( " n = 26 (10 hearts and 10 diamonds) and r = 10. \r
\n" ); document.write( "\n" ); document.write( "C(26, 10) = 26! / (10! * (26-10)!)
\n" ); document.write( " = 10,400,600\r
\n" ); document.write( "\n" ); document.write( "10,400,600 ways to choose 10 hearts and 10 diamonds.
