Need help with finding the bonds defualt risk premium for part b, please thanks

a. The current price of a stock is 65.88. If dividends are expected to be 2 per share for the next three years, and the required return is 10%, then what should the price of the stock be in 3 years when you plan to sell it? If the dividend and required return remain the same, and the stock price is expected to increase by 2 three years from now, by how much the current stock price is expected to increase? b. What is bond's default risk premium; and what will happen to interest rates on corporate and government bonds if the government guarantees today that it will pay creditors if the corporation goes bankrupt in the future
