What is the difference between fuzzy logic and probability theory?

Answer 1

Fuzzy Logic is all about degree of truth what is the Probability theory about the chances of occurrence (or non occurrence) of an event (its chances not truth).

Lets see an example to find out the difference -
Suppose that I'm standing in your office doorway with one foot in your office and one foot in the hallway. It's reasonable to say that I'm half in your office (as in fuzzy logic), but it's not reasonable to say that there's a 50% chance that I'm in your office (as in probability).

Dear Salil

Probability is all about chances of an event, where as fuzzy is about truthness i.e. how much is the truth of an event. See the example of washing machine which comes with fuzzy logic, the catch here is machine decides how much is the degree of dirtiness and sets the clock for washing.
