Chapter 8 Questions 1. Explain why a probability distribution is used to estimate risk and  return. Risky assets rarely product their rates of return—generally, risky assets earn  either more or less than was originally expected. Investment risk is related to  the probability of actually earning a low or negative return. Therefore,  probability distribution is a listing of all possible outcomes, or events, with a  probability (chance of occurrence) assigned to each outcome. 2. Explain the interpretation of a high and low standard deviation. The lower the standard deviation, the tighter the probability distribution, and,  the lower the riskiness of the stock. The higher the standard deviation, the looser the probability distribution, and,  the higher the riskiness of the stock. 3. Explain the purpose for computing the coefficient of variation. The coefficient of variation show the risk per unit of return, and it provides a

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
