52 cards in a deck 
13 in each suit

he shows a card then replaces it, so we haven't changed anything since he replaced the card, still 
52 cards in a deck 
13 in each suit

But he also shows his friend another card right after that, so 
the probability that the first card is diamond and the probability that the second card is diamond, are same

The events are independent.

Let me know if you need more help.
