    We use the Binomial distribution feature on the Casio Classwiz to find the probability of four events. We also use the store feature to carry a value from distribution to calculate mode.

    How would this be done if there are bounds e.g. finding the probability of X when P(8=

      With this calculator, you would have to do two separate calculations and then subtract. Find P(X≤16) - P(X

    • @TheCalculatorGuide
      @TheCalculatorGuide  ปีที่แล้ว +3

      PD is when you have a single value such as P(x=5) where as CD is where you have a cumulative probability, for example, P(x≤5)

      Just check that it is says Casio in the top left and that it is the fx-991EX model too. The are other models of fx-991 with other letters after them.
