PREFERRED TERM

possibility theory  

DEFINITION(S)

  • a theory of uncertainty, reinvented several times in the 20th century to represent situations of partial ignorance, distinguishing between the more or less possible and the more or less certain. The possibility of "A or B" is the maximum of the possibilities of events "A" and "B". Certainty (or necessity) and possibility are linked by a relationship of duality expressing that "A" is all the more certain that "not A" is impossible (impossibility is the complement to 1 of possibility).
