# Risk neutral valuation [closed]

In a world with three possible states (1, 2, 3) and three assets (A, B, C), the payoff matrix looks like this:

$$r_A;_1,_2,_3 = 110, 110, 110$$ $$p_A = 100$$

$$r_B;_1,_2,_3 = 100, 50, 40$$ $$p_B = 70$$

$$r_C;_1,_2,_3 = 48, 40, 36$$ $$p_C = 40$$

Now we add asset D in portfolio:

$$r_D;_1,_2,_3 = 0, 0, 10$$ $$p_D = ?$$

How can one calculate a price of the asset D via risk neutral probability ethod?
