An adversary A is trying to predict the bit s + 1 of G (k) by outputing O if G (k)_1 = 0 and 1 if G (k)_1 = 1. What is the value of Adv_PRG (A)? We build the statistical test A on G by defining the following efficient algorithm A: A (G (k)) = '0' if G (k)_1 = G (k)_s + 1 A (G (k)) = '1' if G (k)_1 is not equal to G (k)_s + 1 What is the value of Adv_Random (A)? 1.0000
