Imagine the deck cards arranged organized from A to K in one direction and each suit orthogally to the A to K arrangement. You can make a count of all the cards which are 7 or diamonds. The deck has FOUR 7's, THIRTEEN diamonds, and this is \"4%2B13-1\". The reason for MINUS ONE is that one of the cards is both a 7 and a diamond; so this is subtracted in order to not count it twice. \r

\n" ); document.write( "\n" ); document.write( "Sixteen cards of the deck are 7's or diamonds.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "NOW shuffle the 52-card deck. Shuffle it well.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Chance of pulling 7 or diamond is \"16%2F52\".
\n" ); document.write( "This is \"4%2F13=0.3077\"...
