You can put this solution on YOUR website!
The 1st 13 cards you draw could all be the
\n" ); document.write( "same suit. Not likely, but possible.
\n" ); document.write( "If you draw 14 cards, there is zero probability
\n" ); document.write( "that they will all be the same suit, and it is certain
\n" ); document.write( "you will have at least 2 cards of different suits.
\n" ); document.write( "If you draw more cards until you have drawn 26,
\n" ); document.write( "it is still possible you have 13 of one suit and
\n" ); document.write( "13 of another suit
\n" ); document.write( "If you draw one more card to make 27, you know
\n" ); document.write( "that you are certain to have at least 3 cards of
\n" ); document.write( "different suits.
\n" ); document.write( "If you keep drawing until you have 3x13 = 39 cards
\n" ); document.write( "it is still possible that you have only cards of 3 suits,
\n" ); document.write( "Drawing one more card makes it 100% certain that you
\n" ); document.write( "have all 4 suits
\n" ); document.write( "So, you must draw 40 cards to know that you have cards
\n" ); document.write( "of all 4 suits
\n" ); document.write( "
\n" );
