A company is considering investing some independent proposals, The proposals with their expected net present values and standard deviations are given in the following table. A B C Expected Net Present Value (in millions) $4.5 $2.4 $3.2Standard Deviation (in millions) 1.4 0.9 1.2
The projects have the following correlations:
a) Calculate the Expected Net Present Values of all the combinations, A+B, A+C, B+C, A+B+Cb) Calculate the co-variance between A and B, A and C, B and C.c) Calculate the Standard Deviations of all the combinations, A+B, A+C, B+C, A+B+Cd) Calculate the probability of negative Net Present Value of all the combinations, A+B, A+C, B+C, A+B+C
