Prime numbers from 1 to 20 are

\n" ); document.write( "The number 1 is neither prime nor composite (if your teacher doesn't feel that way then modify as necessary).
\n" ); document.write( "That makes 8 numbers prime.
\n" ); document.write( "11 numbers composite.
\n" ); document.write( "1 special number (the number 1).
\n" ); document.write( "20 total.
\n" ); document.write( "P(prime)=8/20=2/5
\n" ); document.write( "Without replacement the total number of cards drops to 19.
\n" ); document.write( "P(composite)=11/19
\n" ); document.write( "P(prime, composite)=(2/5)(11/19)=22/95
\n" ); document.write( "
