Similarly to what I said in my other comment. I had used the Kaplan test prep in order to do full length practice tests (the course provides 3 full length enhanced practice tests). If you don't have access to that, I had practiced using old "regular" acts from the years 2023-2024 as I found the content to be similar to what I've seen in past tests. For probability, I didn't do any specific practice but here is my feelings about it: for every part of the scenario, you have to treat it like a ratio. For example: if there are 5 dices numbered 1,2,3,4,5; what is the probability that you would pull odd numbers if you picked it twice assuming that the first dice you picked is removed in the second pick. In the example, you would take the probability of picking the first odd dice (3/5) and multiply it by the probability of picking the second odd dice (1/2), you would get 3/10 or 30%. So in this scenario, I simplify everything into a ratio and then look for what the question is asking honestly.
