Since we did not put the first card back, the total number of cards has now decreased to 2.
So the only possible outcome of picking a 3 and then picking a number greater than 2 is if the second card is a 3.
Therefore, the probability of this happening is 1/2 (since there are only two cards left and one of them is a 3).
You pick a card at random. Without putting the first card back, you pick a second card at random.

What is the probability of picking a 3 and then picking a number greater than 2?

But we don't know how many cards there are!

I apologize for my mistake. Without knowing the number of cards, we cannot calculate the probability of picking a 3 and then picking a number greater than 2.
