### Unit: Introduction

#### Classical Probabilities (50 minutes)

This topic was originally part of Spins Lab 1. There are two problems with that lab. First, that students don't understand the mean as a weighted average. Second, that the effect of binning data is not clear. We are currently working on activities that address these problems. In the meantime, we ignored them for 15 years and you can safely do so also.
