Unformatted text preview: n by first calculating the expected outcome, E(x). In our example, there are three possible outcomes, so N = 3. Adding the probability-weighted outcome of each of these three outcomes results in the expected cash flow: E(Cash flow for Product A) = (0.20) $10,000 + (0.50) $5,000 + (0.30)-$1,000 E (Cash flow for Product A) = $2,000 + $2,500 - $300 E (Cash flow for Product A) = $4,200 The calculations for the standard deviation are provided in Exhibit 1. The standard deviation is a statistical measure of dispersion of the possible outcomes about the expected outcome. The larger the standard deviation, the greater the dispersion and, hence, the greater the risk.
