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.

Probability of 0 is impossible, and 1 is certain. So, probability must be between 0 and 1, inclusive.

No. Probability must be between 0 and 1.

No, it must be a number in the interval [0, 1].

Probability value can only be real number between 0 to 1, therefore, it cannot be greater than 1 or less than 0 or a complex number.

From the related link, you can read directly the probability that Z is less than 1.51 is 0.9345.

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.

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.

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.

No, all probabilities are given from a scale of 0 to 1. 0 represents 0% and 1 represents a 100% probability.

Larger or equal to 0 but less than or equal to 1

No, 0.006 is not a valid probability because probabilities must be between 0 and 1. In this case, 0.006 is less than 0 and therefore cannot represent a probability.

Probability value can only be real number between 0 to 1, therefore, it cannot be greater than 1 or less than 0 or a complex number.
