Normal probability distribution Answer the following questions, assuming that

the rates of return associated with a given asset investment are normally distrib- uted; that the expected return, r, is 18.9%; and that the coefficient of variation, CV, is 0.75.

  1. Find the standard deviation of returns, s.
  2. Calculate the range of expected return outcomes associated with the following probabilities of occurrence: (1) 68%, (2) 95%, (3) 99.7%.
  3. Draw the probability distribution associated with your findings in parts a and b.

4. Statistical measures of standalone risk Remember, the expected value of a probability distribution is a statistical measure of the average (mean) value expected to occur during all possible circumstances. To compute an asset’s expected return under a range of possible circumstances (or states of nature), multiply the anticipated return expected to result during each state of nature by its probability of occurrence. Consider the following case: James owns a two-stock portfolio that invests in Blue Llama Mining Company (BLM)...
