Which term describes the probability that is based on what should happen in a perfect world?

The term that describes the probability based on what should happen in a perfect world is theoretical probability. This concept relies on knowing all possible outcomes of an event and assumes that each outcome is equally likely. It is calculated using a formula that divides the number of favorable outcomes by the total number of possible outcomes. For example, when rolling a fair six-sided dice, the theoretical probability of rolling a three is 1 out of 6, since there is one favorable outcome (rolling a three) out of six total possible outcomes.

In contrast, empirical probability refers to the probability determined through experimentation or historical data, which may not always reflect the ideal expected outcomes. Bias probability, while not a standard term in probability theory, may suggest a distorted view of probability due to emotional or subjective influences. Subjective probability relies on personal judgment or belief about the likelihood of an event occurring, rather than a mathematical basis.
