Here is the sample space of all 52 cards:\r\n" );
document.write( " \r\n" );
document.write( "A♥   2♥   3♥   4♥   5♥   6♥   7♥   8♥  9♥  10♥  J♥  Q♥  K♥ \r\n" );
document.write( "A♦   2♦   3♦   4♦   5♦   6♦   7♦   8♦  9♦  10♦  J♦  Q♦  K♦\r\n" );
document.write( "A♠   2♠   3♠   4♠   5♠   6♠   7♠   8♠  9♠  10♠  J♠  Q♠  K♠  \r\n" );
document.write( "A♣   2♣   3♣   4♣   5♣   6♣   7♣   8♣  9♣  10♣  J♣  Q♣  K♣ \r\n" );
document.write( "\r\n" );
document.write( "Here is the subset of successful drawings, every card that is\r\n" );
document.write( "a king or heart or a red card.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( " \r\n" );
document.write( "A♥   2♥   3♥   4♥   5♥   6♥   7♥   8♥  9♥  10♥  J♥  Q♥  K♥ \r\n" );
document.write( "A♦   2♦   3♦   4♦   5♦   6♦   7♦   8♦  9♦  10♦  J♦  Q♦  K♦\r\n" );
document.write( "                                                        K♠  \r\n" );
document.write( "                                                        K♣ \r\n" );
document.write( "\r\n" );
document.write( "Count them.  I count 28.  So the probability is 28 ways out of 52.\r\n" );
document.write( "In probability theory, \"out of\" means \"over\".  So the probability\r\n" );
document.write( "is 28 over 52, or 28/52 which reduces to 7/13.\r\n" );
