New product development has estimated the profitability for a new product.  The probability distribution of the profitability (millions of dollars) is given below.  Find the expected value (mean) for the profitability of the new product.    xi         p(xi) -100       0.25      0       0.30  100       0.20  200       0.10  300       0.15

An investor can use coefficient of variation (CV) to help determine whether the investment’s expected return is worth the volatility (variability) it is likely to experience over time.
