Because probability is measured from zero to one, where zero means something cannot happen and one meaning it will definitely happen. This can also be looked at as there being a 0% chance or 100% chance of it happening. So obviously there can not be less of a chance than it definitely not happening, so it cannot be less than zero.

Why cannot a probability not be less than 0?
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.
When probability is less then 0 what happen?
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.
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.
Can the probability be more than 1 or less than 0?
No, all probabilities are given from a scale of 0 to 1. 0 represents 0% and 1 represents a 100% probability.
Suppose z has a standard normal distribution with a mean of 0 and a standard deviation of 1. the probability that z is less than 1.15 is?
probability is 43.3%
