The Monte Carlo simulation: a. gives the exact outcome that can be expected from a project. b. uses probability distributions for variables as input data to estimate the project's net present value (NPV). c. produces both an expected NPV (or IRR) and a measure of the riskiness of the NPV or IRR for different scenarios. d. can be useful for estimating a project's market risk. e. calculates NPV for a change in one key variable.
