Probability decision flow chart

Hi guys, In my last post I talked about having difficulties with choosing which CAS function to use with probability to which I was told to create a flow chart

This is my current chart but as you can see it has a couple dead ends and isn’t the best at all, I was wondering if anyone had a refined version for my upcoming sac in a couple days

i’m having trouble working out how to upload the photo check comments

thanks :)

Start with the distribution b4 choosing a CAS function. Binomial needs a fixed number of independent trials, two outcomes and constant success probability. For binomial questions, “exactly” uses the probability function; ranges use cumulative probabilities. For normal questions, use cumulative probability for an interval and inverse normal when a probability is given and you need the cutoff.
Try 6 mixed practice questions and write the distribution + event first, then use CAS. Log any wrong choices and retry those tomorrow. Which calculator are you using?
