document.write( "The number of ways to select one or more students from 6 students is equal to the number of non-empty subsets in the set of 6 students.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "It is very well known fact that the set of N elements has   subsets, including an/the empty subset and the improper subset.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "In your case, N = 6 and the emty subset is excluded, so the number under the question is   = 64-1 = 63.\r\n" );
