9.12Â Â Â Â Â Â Â Â Â Â Â Â Suppose that each of two investments has a 4% chance of a loss of $10 million, a 2% chance of a loss of $1 million, and a 94% chance of a profit of $1 million. They are independent of each other.
a.               What is the VaR for one of the investments when the confidence level is 95%?
b.  What is the expected shortfall when the confidence level is 95%?
c.               What is the VaR for a portfolio consisting of the two investments when the confidence level is 95%?
d.              What is the expected shortfall for a portfolio consisting of the two investments when the confidence level is 95%?
