Answer to Question #190933 in Microeconomics for sushil

Question

Solve five games (either Nash equilibrium or dominant strategy) as an example of oligopoly firm behaviour. 

Answer 1

Nash equilibrium:

The set of players’ strategies for which no player can benefit by changing his or her strategy, assuming that the other players keep theirs unchanged.

You will see that no player deviates from the original option if you show Sam's plan to Tom and vice versa. Knowing the other player's next move has no bearing on either player's action. A Nash equilibrium is described by Outcome A.
