\n" ); document.write( "Red cards: Diamonds and Hearts
\n" ); document.write( "Black cards: Spades and Clubs\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The set of spades is subset of the black cards.
\n" ); document.write( "Meaning the event \"select spade OR black\" is the same as \"select black card\", as mentioned by the other tutor.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The type of cards we have left are: Hearts, Spades, and Clubs.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Two of those card categories are black, out of 3 categories total.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Therefore, we get 2/3 = 0.667 approximately.
\n" ); document.write( "Round that decimal value however needed.
\n" ); document.write( "The 6's go on forever, but of course we have to round at some point.
\n" ); document.write( " \n" ); document.write( "
