Can u please Solve me this ??

Hei i would really appreciate if someone could solve and explain me how these questions are calculated Q) Consider a project that costs $100,000. The project may succeed with probability 0.5 or may fail with probability 0.5. If the project succeeds, it yields a cash-flow of $120,000. If it fails, it yields a cash-flow of $90,000. The project has a beta of 1.2. The risk-free rate is 4% and the expected return on the market is 10%. a) What are the project’s expected, realized, and required returns? b) How much would an investor be willing to pay for the cash-flow stream, given the project’s beta? c) What is the project’s NPV?
