Since you do not put the first card back before selecting the second card, the sample space changes after the first card is selected.
After selecting a 3, there is only one card left in the sample space that is less than 2, which is card 1.
Therefore, the probability of picking a 3 and then picking a number less than 2 is 1/3.
