Consider an investment where with probability 0.9 you gain 10% prot of your total investment and with probability 0.1 you lose 50% of your total investment. Suppose you have a total asset of 20, 000 for investment. Calculate VaRug. Suppose now there is another investment opportunity which has the same probability of gain and loss. Calculate VaR.g_9 of the combined investment if the fund is evenly split in the investments
