$150 or $250 with equal probability. The proportion of informed traders is 40%, whereas the proportion of liquidity traders is 60%. As usual, liquidity traders buy or sell with equal probability, whereas informed traders only buy when they know the security price is high, and sell when they know the security price is low. The probability that V $250, conditional that the first trade is a buy, is: Consider a sequential trade model in which a security has an uncertain value. The value V of the security can either be O a. P(V-250 I Bu): 0.2 b.py 250. Buyl-0.3 C. PIV-250 | Buy]-0.5 a) d. PN-250 I Buy1-07 O e. PN-250 | Buy-0.8 . f. None of the above
