(100,100) |
Group of answer choices
None of the other answers is correct.
a=20, b=140
a=200, b=40
a=160, b=0
a=80, b=150
The structure of the game is equivalent to the prisoners
dilemma. The prisoner dilemma is a game in which one player's
strategy affects the other player. Both the player's try to
maximise their pay off (i.e. make them better off). Each player
chooses the strategy assuming other players strategy.
Here in the given payoff matrix we see when the player 1 and player
both chooses the strategy (R,R) the pay off is (100,100). When the
player 1 and player 2 chooses the strategy (F,F) the payoff should
be same (a,80) so a should be 80. And thus, for the strategy (F,F)
the payoff is (80,80). If both chooses same strategy the payoff for
each player will be same.
The player's if doesn't chooses same strategy i.e. if one chooses F
other chooses R.
The strategy is (R,F) i.e. when player 1 chooses R and player 2
chooses F. So the payoff (40,b) will be (40, 150). And
similarly,
If the strategy is (F,R) i.e. when player 2 chooses R and player 1
chooses F. So the payoff (b,40) will be (150,40).
So, a=80 and b= 150
