There are 13 hearts in a standard 52-card deck.
The probability of getting a heart on the first card is 13 / 52 = 1/4
Given that the first card was replaced, the probability of getting a diamond on the second card is 13 / 52 = 1/4
Therefore, the probability of getting a heart on the first card and a diamond on the second is given by 1/4 x 1/4 = 1/16.
