Hey, I have a question related to game theory, any help is appreicated.

Consider the following collective action game. There are 10,000,000 players, each of whom has two actions: Revolt, or Not. Payoffs are as follows: (1) If at least 2,000,000 people revolt, the revolution succeeds, and everyone gets a payoff of I. (2) If fewer than 2,000,000 people revolt, and individual i revolts, then i gets -1.
