It turns out that it this game there is only one Nash equilibrium in mixed strategies. In equilibrium each player uses the mixed strategy .5 Heads, .5 Tails. Not all such games will have .5/.5 as the equilibrium probabilities but computing the correct probabilities for more complicated games is a topic for more advanced courses.

   While this is technically an "economic" example, it's not exactly an oligopoly example. However, in a number of non-price competition settings such games may arise.
