Answer:
in a region with a letter
Step-by-step explanation:
For a certainty, then probability is 1.
That means sum of probability of all events in the sample space.
This means P(A)+P(B)+P(C)+P(D)=1

Hence for certainty, the region must be:
A or B or C or D
So the correct answer is in a region with a letter.
