Best Answer Explained in Below-:

The correct answer to the question "What is the probability of impossible events?" is actually B) 0, not C) >1. It's important to clarify the nature of probability itself as it ranges between 0 and 1.

In probability theory, an impossible event is defined as an event that cannot occur under any circumstances. For example, the probability of rolling a 7 on a standard six-sided die is impossible, thus its probability is 0. The scale of probability reflects the likelihood of an event occurring; 0 indicates impossibility, 1 indicates certainty, and any value between those represents varying degrees of likelihood.

To summarize, an impossible event will always have a probability of 0, aligning perfectly with the fundamental principles of probability theory. Therefore, options A), C), and D) misrepresent the definition of an impossible event, as none can exceed the bounds of 0 or 1.
