Because probability is a measure of how likely it is that some event will occur. If there is no chance at all that the even will occur than the probability is 0. If it will occur with 100% certainty, then it is 1 or 100% A negative number would have no meaning in terms of how likely an even is to occur?
The term is probability (theoretical probability), or how likely a given event is to occur.
