ok for q5, this is how I did it
start off with a state space, call it 0 (zero).
if you claim, you go to state space 1
if you claim again you go to state space 2
if you don't claim you go from 1 to 1-
you can go back from 1- to 1, if you claim
you can't go from 1- to 2, as you must go through 1, but you can return from 1- to 0 if you don't claim
for you to be at state space 2 then you must have claimed for last 2 years. you get to state space 2 from either 0->1->2, or 1- -> 1 ->2. if you're at state space 2 and you claim then you stay at state space 2 with the probability 0.25. If you don't claim you can go to 1-.
if you're at state space 1 or 1- then you must have claimed just once in last 2 years. to go from state space 1 to 2 you need to claim and it's with probability 0.15. Also to go from 1- to 1 is probability 0.15
if you're at state space 0 then you must have not claimed for last 2 years, so probability of claiming and moving to state space 1 is 0.1
you can fill the rest in
