No. Probability must be between 0 and 1.

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

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.

There are many such events. The probability of throwing a 1 or 2 on one roll of a die, for example.

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. Probability must be between 0 and 1.

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

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

certainty (no doubt), probability or likelihood (greater than 50% chance), possibility (greater than 0% but less than 50% chance)

There are many such events. The probability of throwing a 1 or 2 on one roll of a die, for example.

probability is 43.3%
