please help me find the WACC, NPV, and expected value of this example in both case scenarios.

You know that the assets of a firm SKIP are today worth $100 million. You reasonably feel that in a year they will be either worth $110 million or $90 million. You also know that a treasury bill maturing in one year is offering today a yield of 5%. The firm has a zero-coupon bond that matures in one year and has a face value of $100 million
