document.write( "The probability is the ratio of the number of all possible pairs chosen from 15 girls \r\n" );
document.write( "to the number of all possible pairs chosen from all 15+10 = 25 students.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The numerator is   =  = 15*7 = 105.\r\n" );

document.write( "\r\n" );
document.write( "The denominator is   =  = 25*12 = 300.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "The ratio, i.e. the probability under the problem's question, is  P =  =  =  = 0.35 = 35%.     ANSWER\r\n" );
