Consider a 5-year risky corporate bond that pays a coupon of 7% per annum (paid semiannually). The yield on the corporate bond is 8% per annum (with continuous compounding). The yield on a similar risk-free bond is 6% per annum (with continuous compounding). 

a) What is the price of the risky bond and the price of the riskfree bond at time t=0?

b) Let Q denote the constant unconditional probability of default per year. Assuming that defaults can happen at times t=0.5,1.5,2.5,3.5 and 4.5 year (immediately before coupon payment dates), calculate the expected loss from default in terms?
