\n" ); document.write( "\n" ); document.write( "Depends on whether you replace the first card into the deck before you draw the second.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "With replacement the answer is yes, they are independent events.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Without replacement, no. That's because the probability of the second card being a spade is either 13/51 if the first card drawn was other than a spade but it is 12/51 if the first card was a spade.\r
