Consider the Prisoner's Dilemma with the following characteristics: if no one confesses, both get 1 year in prison. If one confesses and the other one does not - the one who confesses goes free, and the other one gets 7 years. If both confess, they get 5 years each. What is a rational strategy here and what is mathematical expectation of the outcome here? Confess, 7 years Confess, 2.5 years. Do not confess, 4 years Do not confess, 2,5 years Do not confess, 5 years Confess, 1 year Do not confess, 1 year
