You are trying to set up a portfolio that consists of a corporate bond fund and a common stock fund. the following information about the annual return (per \$1,000)of each of these investments under different economic condition is available, along with probability that each of these economic conditions will occur:
probability economic corporate common
conditions bond fund stock fund
0.10 Recession -\$30 -\$150
0.15 Stagnation 50 -20
0.35 Slow growth 90 120
0.30 Moderate growth 100 160
0.10 High growth 110 250

Compute the covariance of the corporate bond fund and the common stock fund.
