Quick question, I'm following the explanation in ASET for this question and my initial approach was WAY off, however when I compare the end result they're virtually identical (i.e. diff of 0.00001 for a dependent probability).
My approach was to evaluate mu(a) @ X = 40, add that to mu(b) of 0.03. Get the survival probability, then the cumulative decrement probability. Then apportion the decrement probability as a proportion of mu(a)/[mu(a) + mu(b)]. I get 0.029345 vs 0.02934 in ASET.
Is my approach in correct? I ask as it took me under a minute to calculate for a 7 mark question, with virtually identical answers. That time savings would be precious for Monday's exam. Thanks.
