2,3,5,7 are the prime numbers in the deck.
\n" ); document.write( "Since there are 4 suits, that makes a total of 16 primes in 52 cards.
\n" ); document.write( "P(prime)= $\"16%2F52=4%2F13\"$
\n" ); document.write( "P(not prime)= $\"36%2F52=9%2F13\"$
\n" ); document.write( "If the first card is not prime, then for the second draw.
\n" ); document.write( "P(prime)= $\"16%2F51\"$
\n" ); document.write( "P(2nd card prime, 1st card not prime)= $\"%2816%2F51%29%289%2F13%29=48%2F221\"$ \n" ); document.write( "
