Hello 1. Why is 2P73 * 4P75 = exp(-2 * 0.02) * exp(-4 * 0.04) used instead of 3P73 * 3P76 = exp(-3 * 0.02) * exp (-3 * 0.04)?? This is because I...

Hi Rahul This is a tricky concept and Core Reading doesn't go into any detail here! This section is describing parameter estimation using the...
Hi Hariram Double check any information that you receive from the IFoA; however, as far as I know, the April 2024 CS2 exams will be sat in the...
Hello (n-1) choose (n/2 - 1) is (n-1)! / [(n/2 - 1)! * (n/2)!]. Let's call this A. (n) choose (n/2) is n! / [(n/2)! * (n/2)!]. Let's call this...
Paper A is 70% and Paper B is 30%. This is set out here: https://actuaries.org.uk/qualify/after-exams/marking-guidelines/
Hi Fiorentinaa You are correct, it should just become tpx^24 as you say. As far as I can tell, that's what's in the solutions. Would you be...
Hi Rahul Say mu(x) = 0.007377, n = 100,000 and we are considering the period of 1 day. Assuming 365 days in a year, then h is 1/365. The number...
