Answer:
-0 and 1 represent a probability value
2 and -1 never represent a probability value.
Step-by-step explanation:
Probability values should range from 0 to 1. The probability of 0 means there is no chance and of 1 means probability is really certain
So any number range from 0 to 1 will be great like: 0.5; 0.9 ...
and any number outside the range of 0 to 1 is not realistic. Values like 2 or -1 do not represent probability values.
