Probability using Binomial Distribution on a Casio Classwiz fx-991EX fx-570EX Calculator A Level

[@davidhill8163]

Many thanks for this, it was a great help as I dont find this topic easy.

[@MagnificentCreature]

I cannot seem the store the result to A?

[@samueljhughes]

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

[@TheCalculatorGuide]

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

Hey,can cie a level further math use a calculator like this?with binomial cumulation distribition.

[@njwtrmz2635]

i cannot store to A

[@Osamah001]

How do i know when to choose Binomial PD or Binomial CD ??

[@TheCalculatorGuide]

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)

@@TheCalculatorGuide ok thanx and what about normal the same thing ?

[@careervest]

thank you so much

[@IKIN_10]

i dont have the distribution option in my fx991, same one as in the video.

[@TheCalculatorGuide]

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.
