I think you also need to change this statement.

No I just say that b/c it is convenient. I know it isn't exactly correct, but it is a heck of lot easier and faster to say.

i have a quick question. For a population which contains equal numbers of males and females at birth:

For males
For females

find q60. this is question 4.36 with asm. when solving the problem [IMG]http://www.actuarialoutpost.com/cgi-bin/mimetex.cgi?l_{60}^{m}\, =\, e^{-.1*60}=0.002478752[/IMG] was used in placed of tpx. Why. I am a little confused because above is tpx under constant force. how can lx be used. Can you explain.

sorry I tried to copy and past from the 4.36 thread, but if you can follow the tread under mlc maybe you will understand.

I'm sorry but I'm not clear on what you are asking. This is B.1 #169 in the TIA problem sets. There is a couple of ways you can work this problem. Here is one way:

This is a simpler way to solve the problem than in the tread for asm 4.36.
I am still wondering, however, when the person solved the problem in the tread, they used under the constant force of mortality tpx for the male(constant force also applies to the females in this problem) is exp^(-.1 x 60) but instead of using the notation tpx they used lx(male) is exp^(-.1 * 60). I want to know why did they used lx instead of tpx. Are lx and tpx, the same thing is this problem.

sorry s(x) = e^(-ux) so are lx and s(x), the same thing, in this problem.
