Final answer:
The scenario where each outcome of an event is equally likely to occur is described by a uniform probability. This is distinct from conditional, independent, and mutually exclusive probabilities. The correct option for the described scenario is 'd. Uniform Probability'.
Step-by-step explanation:
In the context of probability, when each outcome of an event is equally likely to happen, it is referred to as a uniform probability. The uniform distribution is a type of probability distribution that assumes that all outcomes are equally likely. This is in contrast to conditional probability, which depends on a given event, independent probability where outcomes do not affect each other, and mutually exclusive probability, where the occurrence of one outcome prevents the occurrence of another.
For example, if you were to roll a fair six-sided die, because it is fair, you expect that each number (1 through 6) has an equal chance of appearing after the roll. This scenario is reflective of a uniform probability distribution, illustrating the concept of events that are equally likely to happen.
The correct option that describes the probability where the occurrence of each outcome is equally likely to happen is the option d: Uniform Probability.
