Select a card from the deck. Place the card back in the deck. Select another card. What is the probability that both cards will be black?

Would it be 13/26 or 50%?

No. There are 26 black cards in a 52 card deck. You put it back so there are 52 cards again to choose from. So, you have 26/52 again.
