2. Consider this as a payo' matrix, where payoffs for the shooter (row player) are equal to these frequencies and payoffs for the goalie are 1 minus the frequency. (a) Show that there is no Nash equilibrium in pure strategies (mean ing, without randomizations) (b) Find the equilibrium in mixed strategies (9L, 3;) that correspond, respectively, to the probability that goalie will go left and the probability that the shooter will shoot left. (I taught this in my lecture, but you can also search the web for \"computing mixed strategies\" or can view the following great lecture in youtube: How to construct strategy equilibrium
