3. (4 points) Modify the two-bidder example above and allow only three possible bids, 0, 1/2, or 1. Let q = 2/3. (a) In a first-price auction, what are the symmetric Nash equilibria? (b) In a second-price auction, is bidding one't true valuation still a weakly dominant strategy? Conclude whether or not the strategy profile in which each bidder bids one's true valuation is a Nash equilibrium. Are there other symmetric Nash equilibria
