Weekly Problems for Fall '05

I too got the same thing as Scottie

Sorry if my explanation wasn't very good. If you look at e(circle) 20 and e(circle) 26.3, notice that the expected future lifetime lasts until age 61.2. Because of this, current age doesn't matter between the ages of 20 and 26.3. Every life in that age range will be expected to live until age 61.2 e (circle) 21 = 40.2, e (circle) 21.3 = 39.9, etc.

If you realize this, then you can also deduce that tpx =1, as long as 20 <=x<=26.3.

If you like recursions, you know e 24:2 = p24 + p25. Since p24 = 1 and p25 = 1, e 24:2 = 2.

Hope this makes more sense!

Minor point that doesn't make a lick of difference here, but:

e_24:2 = 1_p_24 + 2_p_24 = p_24*(1 + p_25)

You're right, my mistake. Those careless errors always end up costing me when it comes to exam time.

I get .1885 for the premium on number 2.

[KAJ7481]

I got 0.2, how did you get 0.1885?

Just so there's a record of it, I unstuck this thread:

and made this one the new sticky.



Good Luck, study hard, and don't be this guy in line on exam day

That's what I got too, but that seems to be too easy.
