- D
Solution & Step-by-step Explanation
In a standard Venn diagram representing this question:
* One geometric shape represents 'Red' objects.
* Another shape represents 'Plastic' objects.
To find "red objects that are not plastic", we look for the region inside the 'Red' shape that does not overlap with the 'Plastic' shape. In this standard problem configuration, the number corresponding to this region is .
* One geometric shape represents 'Red' objects.
* Another shape represents 'Plastic' objects.
