Dealing with unknown variables. Making predictions. Examples of subjective probability. Pros and cons of subjective probability. Requires little mathematical or historical data Good for making guesses and predictions Uses an individual's past experience and professional opinions.

In subjective probability, the percentage of your prediction may change based on the previous flips. If the same coin has been flipped 15 times in the past and has given ten times heads up and five times tails up. Though it is mathematically incorrect, your experience has created a situation that compels you to predict using subjective probability.

The weather department is predicting that it will rain in the next 2 hours based on wind pattern, weather situations, and their software analysis. But you may have the same predictions of rain in the next 2 hours based on your experience with weather or rain.

It also consists the likelihood of certain outcomes emanating from the occurrence of an event. Generally, a mathematical approach is deployed in calculating the likelihood of an event. Subjective probability is a type of probability that is derived from the opinions of individuals in the likelihood of an event. Hence, personal biases and beliefs can affect subjective probability.
