np.random.choice()

In this exercise, you will be introduced to the np.random.choice() function. This is a remarkably useful function for simulations and you will be making extensive use of it later in the course. As a first step, let's try to understand the basics of this function. Using help(), figure out which of the following input parameters are not optional for the np.random.choice() function:

This chapter gives you the tools required to run a simulation. We'll start with a review of random variables and probability distributions. We will then learn how to run a simulation by first looking at a simulation workflow and then recreating it in the context of a game of dice. Finally, we will learn how to use simulations for making decisions.
