document.write( "\r\n" );
document.write( "(a)  It means that you chose all 3 yam tubers from the set of 15-5 = 10 yam tubers that are not spoilt.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "     Therefore, the probability (a) is  P =  =  =  =  = 0.2637.         ANSWER\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "(b)  It means that you chose all 3 yam tubers from the set of 5 yam tubers that are spoilt.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );

document.write( "\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "(d)  In this case, the probability is the COMPLEMENT to case (a)  P = 1 - 0.2637 = 0.7363.      ANSWER\r\n" );
