1) there are four suits, so the chance of the drawn card being a heart is 1/4\r
\n" ); document.write( "\n" ); document.write( "2) The chance of a head on each roll is 1/2, so for both tosses to be heads it's 1/4. (Both tails, 1/4, and one head one tail, 1/2)\r
\n" ); document.write( "\n" ); document.write( "3) We expect about 50, although precisely 50 would be a bit less common.
\n" ); document.write( "
