The statement "Probability refers to a number between 0 and 1 (inclusive), which expresses the chance that an event will occur" is True.

Explanation

Probability is a fundamental concept in statistics and mathematics that quantifies the likelihood of an event happening. It is defined on a scale from 0 to 1, where:

• A probability of 0 indicates that the event is impossible and will not occur.
• A probability of 1 indicates that the event is certain and will definitely occur.
• Any probability value in between (e.g., 0.5) signifies the degree of likelihood that the event may happen; for instance, a probability of 0.5 means there is an equal chance of the event occurring or not occurring.

In practical terms, probabilities are often expressed as fractions, decimals, or percentages. For example, a 25% chance of rain corresponds to a probability of $P = 0.25$, indicating a relatively low likelihood. Thus, given the definitions and characteristics of probability, it is correct to say that it is a number between 0 and 1 which represents the likelihood of an event occurring.
