Casio fx-ES Plus: Z-Score Probabilities & Normal Distribution Areas (NO Z-TABLE!)

Tired of flipping through Z-tables in your Statistics or AP Stats class? This quick tutorial shows you how to use the built-in Distribution (Distr) functions on your Casio fx-ES Plus series calculator (including models like the Casio fx-991ES Plus, fx-300ES Plus, etc.) to instantly find standard normal distribution areas and probabilities. Learn the difference between the P(, Q(, and R( functions and how to format your results to the standard four decimal places using the FIX setting.
