Certain.

Why?

If something has a probability of 1, then it is always going to be certain. If something has the probability of .5-.9 then it is likely. .1-.4 is unlikely, and 0 is impossible.

AKA decimals are used to represent likely and unlikely scenarios. 0 is used to represent impossible, and 1 for certain.
