It was #3  one thing I didn't catch at first was that you wanted the probability of being alive (healthy OR sick, but NOT dead) at the BEGINNING of t=3 which is the end of t=2. I was calculating probability of being healthy only which and combining sick with dead. After realizing the syntax error I corrected my calculations and got something that made more sense and one of the answer choices.

How did you guys calculate the variance of the 10 pay annuity at time 5 where they give you premium is 166.5 or something? This was one of the written answer, later they ask for covariance of the whole life insurance and term annuity which I also couldn't get
I also couldn't get the premium for the common shock model. Or the pv of the benefit when the guy dies after the girl Also, what is the Kolmogorov forward differential equation for tpx in state j? Why only one state? Last edited by hunkal; 10272017 at 10:18 PM..

(P/d)^2*Var(v^Kx+1) (P/d is a constant and variance of a constant is zero). You will then recognize Var(v^Kx+1) as variance for an insurance item (this was a simplified approach, use appropriate corresponding annuity/insurance relation). I couldn't prove the premium for the common shock model question  at this point I had lost steam and still had to get to the last question.

This is correct and the answer was E. The AV without the CF was larger then the AV with the CF which means the CF is in play. The question asked for the ADB which would be 1.5AV. If you did not use the CF and just did ADB = FA  AV you would have got choice A which is not correct.

Of course this was one of last few concepts I started understanding better in the last month so maybe my calculations could have been off.
