Hi Rimsha, I saw your post, and although I have not taken the test yet, I have collected resources throughout this thread. A good resource would be first to go back and scan for the high score gouges, usually they will have posted a study guide along with them that has a math section where probability problems are present, around page 260 has a great one. As far as studying further, another great resource for generating probability problems is kuta software–see attached. You can google them and they have plenty of high level math worksheets, I attached two related to probability, specifically algebra 2 related. Start with the second attached file!
I have not taken the test yet, and I am not sure how in depth these probability questions get–if you could provide some examples of questions you received that would be great! I have been putting a lot of my focus towards exponential equation type problems, word problems etc., and a few probability. I'll definitely be looking more into these.
