# STEP Support - Assignment 6

### Introduction

This STEP support module covers arrangements and some problems with probability. Previous assignments can be found here, but you can do this one without having done the others first.

STEP questions are difficult, they are supposed to be and you should expect to get stuck. However, as you tackle more and more STEP questions you will develop a range of problem solving skills (and spend less time "being stuck").

The final question is about conditional probability, and how very different $P(A|B)$ and $P(B|A)$ can be.
