Game Theory Question: Please find all symmetric Perfect Baynesian Equilibria and show all work, thanks

2. Consider a modied public good game between three players in which for the public good to be available at least two players out of the three have to contribute. If the public good is available each player gets a payoff of 1 from it. The cost of contributing for player i is equal to Ci. Each player knows his or her own cost and has incomplete information about the other players costs believing that the cost of each opponent is uniformly distributed on the interval [0, 1] independently of each other. Find all symmetric PBE of this game
