Describe the difference between events that are certain, likely, equally likely, unlikely, or impossible. (You don't have to start with "What is...")
Certain would be 100% of the time, likely is anything greater than 50% of the time, equally likely is exactly 50% of the time, unlikely is anything less than 50% of the time, and never is anything that has a 0% chance of occuring.
