The history of the decision analysis is not that long, however. In 1730s Daniel Bernoulli (1738) first used the concept of utility when explaining the evaluation of a particular uncertain gable known as St Petersburg paradox. ... fdlgdflkgjdflgk jdlfkgj lkfjg kslkdjglkfjglfgjldfgjldfjgldjgldfjglk dflglkdjdgjlk jdlkgj reotiuoert dfgdf dfg fg fgd eteroituertfg fgdg fgryko ertuertiueryituyertret LMML LOM XSL XML Visual representation HTML PDF ljflkj sdlkfjlsd dksjflkj sdflksdjf ljflkj sdlkfjlsd dksjflkj sdflksdjf
