- an odd prime number under 10 given the card is a club. (1 is not prime.)

There are 4 primes less than 10: 2,3,5,7

And 13 clubs.

- a Jack, given the card is not a heart

There are 3 Jacks that are not Hearts (Clubs, Spades, Diamonds). Each suit has 13 cards.

- a King given the card is not a face card

This one is a 'gimme'. Think about it. A King IS a face card.

So with it having to be an "odd prime number" on the first part, would the 2 still be a factor?
