Probability can not be less than 0 or greater than 1. A probability of 0 means there is no possibility whatsoever of an event occurring. A probability of 1 means that the event is guaranteed to occur no matter what.

Does something that can never happen have a probability of 0?

Yes, a probability of 0 is something that cannot happen.


Can a probability be more than 1 or less than 0?

No. A probability of 1 means something will definitely happen. There cannot be a greater certainty than that, so probability cannot be greater than 1. 0 means there is no chance of something happening. You cannot have less than no chance of something happening. So a probability cannot be less than 0.


Why probability always lays 0 to 1?

0 represents that is will never happen. It means that there is no probability that it will happen. 1 represents that is is certain to happen. You cannot be more certain than definitely certain, and something cannot be less probable than not at all.

Why probability is greater than 0 less than 1?

Probability is defined in such a way that 0 (or 0%) means that something is impossible to happen, and 1 (or 100%) means that the event is inevitable. Anything in between means that it MAY happen. Anything outside that range doesn't make sense.


Why cant a probability be less than 0?

How would you interpret such a probability? - A probability of zero means that something is IMPOSSIBLE, while a probability of one means that it is SURE TO HAPPEN. Anything in between means that it MAY happen - the closer to 1, the more likely it is to happen. Anything outside of that range simply doesn't make sense.
