Hi, I have a query in in the example on page 19 of chapter 9. Can anyone explain me the last part of it, the last equation, where we arrive at 5px (infinity)q(x+5):y(1)? Thanks for help! Regards, Shyam
X to die 5 years after Y. So X needs to survive when Y dies. \( _5P_x\) is probability that age x will survive for 5 more years. \( _\infty q_{x+5:{y}^{1}}\) is probability that y dies before X at any time ( So infinity ) conditioning that X to die 5 years after Y's death. To achieve this X needs to survive for 5 years after Y's death. Which is \( _5P_x\)
