Consider a three-year project in which all cashflows are assumed to occur at the end of each year and a risk discount rate of 10% pa is used to evaluate the project. A particular risk may occur at the end of one of the three years, but it can occur only once in the lifetime of the project. If it occurs at the end of Year 1, which event has a probability of y, the consequent cashflows are 1 at the end of each of the three years. If it occurs at the end of Year 2, which event has a probability of ., the consequent cashflows are 2 at the end of each of Years 2 and 3. If it occurs at the end of Year 3, which event has a probability of y, the consequent cashflow is 3 at the end of Year 3. Determine the expected net present value of the cashflows at the start of the project
