Do you put back the each card after you draw it or not?

Nah, it won't. If you are playing poker then it will look like that, the difference is, 9 cards will draw.

Thanks man! My answer is correct, it's

**77%**.

You should add all the probability of getting 1 pair, 2 pairs, 3 pairs until 4 pairs. Why? because the problem stated "atleast" means there are chances that 2pairs-4pairs will show when we draw 9 cards. This is my Prelims Exam so I just wanted to know if my answer is correct and yeah my solution is right!

This is a proof also that I studied and memorized it until I got home

Because some people might judge me.
