Subjective probability is based on personal feeling, experience, or judgment. Objective probability is based on statistics, experiments, and mathematical measurements.
The probability that an event will occur is expressed as a number between 0 and 1. If the probability of an event equals 0, there is a 0% chance that the event will occur. If the probability of an event equals 1, there is a 100% chance that the event will occur.
This is an example of the complement rule, which states that the probability that event A does not occur is 1 minus the probability of A. In statistics, the complement of an event is the event not occurring.
Objective probability is based on personal feeling, experience, or judgment.
