The probability of picking a 3 and then picking a 4 without replacement is calculated as follows:
There are 4 cards in total that can be picked without replacement.
The probability of picking a 3 is 1/4.
After picking the 3, there are only 3 cards left to pick from.
The probability of picking a 4 after picking a 3 is 1/3.
Therefore, the probability of picking a 3 and then picking a 4 without replacement is (1/4) * (1/3) = 1/12.
I hope this helps! Let me know if you have any other questions.
