In this article, you will understand the difference between fuzzy logic and probability.

## Fuzzy logic

It is a many-valued logic where the truth value of variables may be a real number between 0 and 1, including 0 and 1. Everything is associated with a degree.

• It is based on natural language processing.

• It can be integrated with programming.

• It is best suited for approximation.

• It is generally used by quantitative analysts.

• It helps understand the concept of vagueness.

• It captures the meaning of partial truth.

• The degree of membership is in a set.

• It is used in air conditioners, facial pattern recognition, vacuum cleaners, transmission systems, and subway control systems.

## Probability

It is a branch of mathematics that deals with numerical descriptions of how likely an event is supposed to occur, or how likely a proposition is true.

• The value lies in the range of 0 and 1.

• It can’t be used for high approximations.

• It captures partial knowledge.

• It deals with the likelihood of the occurrence of an event.

• It can’t capture any type of uncertainty.

• It can only give a numerical value of whether an event can occur, and how many chances that it would be possible.

• The probability event is in a set.

• It is used in the field of manufacturing, decision-making, risk evaluation, scenario analysis, long-term gains, and losses calculation.

Both are terms to express uncertainty but in different ways. It informs you how uncertainty changes over a period when new data comes in.

Consider the following 2 examples

Example 1 − There is a 59 percent chance that there will be a storm today.

Example 2 − The weather will be stormy today.

Example 1 suggests a percentage/probability that is a number.

Example 2 is fuzzy, there is no clarity about the severity. The statement is subjective.
