document.write( "In all, there are  \"C%5B14%5D%5E2\" = \"%2814%2A13%29%2F2\" = 91 different pairs.\r\n" );

document.write( "\r\n" );
document.write( "When we select only the pair of 2 white shirts, it means that we select from 10 white shirts.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore, the number of all different pairs of white shirts is  \"C%5B10%5D%5E2\" = \"%2810%2A9%29%2F2\" = 45.\r\n" );
