you can use a calculator to try and multiply all of them so multiply 6x4 and then it will give you the answer then once you have that answer multiply it with the 4 im pretty sure but if not then sorry
The answer is 1/5, or 0.2, because if you're always putting the slip back in, then there will always by 5 slips to choose from, therefore making the probability 1 out of 5. I hope this helps!
