I have some problems on this question. The final question I got a answer: 1.9% but it is not right. Can anyone help me? Thank you!

Consider a simple rm that has the following market-value balance sheet Asset Liabilities end equity $1 050 Debt 3410 Equity 640 Next year. there are two possible values for its assets. each equally likely: $1 'IBO and $960. its debt will be due with 4.8% interest. Because all of the cash ows from the assets must go to either the debt or the equity, it you hold a portfolio of the debt and equity in the same proportions as the tirrn's capital structure, your portfolio should earn exactty the expected return on the rm's assets. Show that a portfolio invested 39% in the firm's debt and 61% in its equity will have the same expected retum as the assets of the rm. That is. show that the rm's pre-tex WACC Is the same as the expected return on Its assets. If the assets will be worth $1 180 in one year, the expected return on assets will be 12.4 %. (Round to one decimal pleoe.) It the assets will be worth $960 in one year. the expected return on assets will be - 3.6 %. (Round to one decimal place.) The expected retum on assets will be 1.9 %. (Round to one decimal place.) For a portfolio of 39% debt and 61% equity, the expected retum on the debt will be Do. (Round to one decimal place.)
