AOT limited is considering two mutually exclusive projects - cable and satellite. The possible NPVs for every project and their associated probabilities are as follows:
Cable: Satellite:
NPV ($'000) Probability NPV ($'000) Probability
10 10% 15 60%
20 50% 20 20%
25 40% 40 20%
Determine the standard deviation for every project. Which project has the higher level of risk?
