Exercise 30

It was claimed that Nash equilibria tend to come in odd numbers, yet Table has an even number. The resolution of this seeming contradiction is that Nash equilibria come in odd numbers unless there are ties between payoffs in rows or columns. Show that an odd number of Nash equilibria result in Table if some of certain payoffs are tweaked to break ties.
