There are 13 hearts and 13 diamonds in a 52-card deck.
When Kit picks a card, the chance to draw a heart is 13/52
When Oscar picks a card, if Kit has replaced the card he drew into the deck, he has a 13/52 chance to draw a diamond. 
If Kit has kept his card, then there are 51 more cards in the deck and the chance for a diamonds is 13/51.

The correct answer is either 13/52*13/52 or 13/52*13*51, depending on what Kit does with his card.
