# Sample spaces for compound events

Practice checking if sample space diagrams match a compound event.

### Problem

Elroy and Rose are at Schematic to buy a school planner. There are 3 colors (pink, red, and blue) and 2 formats (lined and unlined) offered. They each created a display to represent the sample space of randomly picking a color and a format.
Whose display correctly represents the sample space?
Please choose from one of the following options.
