\r\n" );
document.write( "There are three drinks for each to choose from, and the probability is 1/3 \r\n" );
document.write( "for every drink to be selected by Seth and/or by Anna, independently.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "Therefore, the probability that both of them will select coke independently is\r\n" );

\n" ); document.write( "\n" ); document.write( "It consists of 9 pairs (drink_Seth,drink_Anna), so you have 9 possible outcomes
