This is illustrated by the TV serial Star Trek fictional character Mr. Spock, who could state the probability of a unique, future event with great precision. This note looks at some basic properties of probability and considers the appropriateness of using probability to demonstrate the impossibility or inevitability of the origin of life. The frequency theory of probability is popular among many scientists and some philosophers. This theory defines probability objectively in terms of the frequency of occurrences in long runs. Not all events in the real world need to be treated probabilistically.
Some phenomena always produce the same deterministic outcome under specified identical conditions.
An illustration is the way an object falls to the ground with constant acceleration due to the force of gravity. Thus constant, static conditions yield a result which can be predicted with a great degree of certainty for a deterministic process. In contrast are nondeterministic or random events where repeated observation under constant static conditions do not always lead to the same outcome. A popular example is the result of a coin toss. Consider a coin that is tossed many times.
