A box contains 2 green and 3 white balls. A ball is selected at random from the box. If the ball is green, a card is drawn from a deck of 52 ca rdto. If the ball is white, a card is drawn from the deck consisting of just the 16 pictures.

document.write( "of 52. Perhaps this problem considers Aces to be picture cards. But I will\r\n" );
document.write( "assume there are 16 picture cards anyway)\r\n" );
