rewrote as

p_{[58]+2}+p_{[58]+2}*(e_{61}) . because it was 3 year select period.

To get e_{61}, use recursion property: e_{60}=p_{60}*(1+e_{61}) because they gave us what e_{60} was equal to.

plug e_{61} back into exspression for e_{[58]+2}, evaluate, then you have

e_{[58]+2}. After that, add 0.5 to e_{[58]+2} to get the complete expectation of life aged {58}+2.

My gut feeling is the mistakes happened here:



when calculating e_{61}

some people might have calculated using the following:

e_{60}=p_{[58]+2}(1+e_{61}), but I do not think p_{[58]+2} should have been used here, instead p_{60} should have been used.

Just my thoughts. I cannot remember my answer, but I am pretty sure I used

p_{60} instead of p_{[58]+2} in the expression for e_{60}, to solve for e_{61}.

I hope I got this one correct, I really do. I am probably missing something here though. I burned about 12 minutes on this problem. Not smart, but it was in the last half hour of the exam and I was just trying to wrack up as many MC points as possible.
I did the same thing and found 1.6 which was b) . Why you think that you have done a mistake ? You didn't arrive to an answer ?

Hey Hach,

I was just having doubts and being a pessimist.

I guess I just wasn't sure if I used p_{[58]+2} or p_{60}

in the expression for e_{60}, to solve for e_{61}.. but I know I should have used p_{60}. Now that I think back to moments where I glanced at my scantron, I think I did have B for that question.

ha.. I didn't actually use v on the exam, but I spaced here when I was writing the formula.

but yeah no v. for e60, it would be e60 = p60 * (1+e61), not p[60] (or any select probability for that matter), because e60 is indicating that the member would have been selected at sometime age 57 or earlier

Word, I agree with you.

I am using the {} to denote subscripts. So, p_{60} in my language is really just p60.

I think we are on the same page!

that's what i did as well. maybe it was a calculation error?

Does anyone remember what number the 95th percentile question was on the multiple choice?

Aw man. Hopefully I will get some partial credit. I was getting so frustrated when I couldn't figure out what I was doing wrong

Do you remember anymore details about the question? I can really remember it. Was it ILT and discrete?

I think it was 11.

11 was the one I guessed on - I was getting answers in the 40000's and all the choices were in the 60000's.
