Calculate risk-free rate and risk-neutral probability

Suppose that over the next year, one of three things could happen to a company's credit rating. It could remain investment grade, drop to non-investment grade or default. The value of a credit derivative that pays $100 in 1-year if the company's credit rating remain investment grade is $93. The value of a credit derivative that pays $200 in 1-year if the company's credit rating drops to non-investment grade is $7. The value of a credit derivative that pays $300 in 1-year if the company defaults is $6. Calculate the risk-free rate and the risk-neutral probability of default.
