Two cards are drawn with replacement from an ordinary deck of 52 playing cards. What is the probability that the first card is a heart and the second card is a diamond?

13/52*13/51

Um, possible typo there?
If the cards are drawn _with_ replacement, the first card is back in the deck when the second is drawn, and the probability of the second being a diamond is again 13/52?
