Simple Coding of Statistical Simulations

Auteur: Nevil Hopley

Onderwerp:  Wiskunde

Tags: Elektriciteit, Fysica, STEM

We will show you how to construct simulations of experiments of chance. We shall use the minimum amount of code, aiming to use just the Calculator and Data & Statistics applications as much...
