an exchange rate has a given expected future value and standard deviation.
A. assuming that the exchange rate is normally distributed, what are the probabilities that the exchange rate will be at least 2 or 3 standard deviations away from its mean?
B part is about chebyshev's inequality. but im sure, if any one could possibly explain the A part, i will get the B.
thank you |
