An overworked math professor is considering a combined life insurance/long-term disability policy that costs $550 for one year of coverage. The policy pays out $120,000 in the event of his death, and $20,000 if he survives but misses more than 6 months of work for medical reasons (called “long-term disability”).
Based on the professor’s profile, it is estimated that he has a .986 probability of surviving with no long-term disability, a .012 probability of surviving but with a long-term disability, and a .002 probability of not surviving the year at all.
What amount of profit should the insurance company expect to make if the professor buys this policy?

because its not ur topic and its not for is for homework not that.

step-by-step explanation:

pay attention in your classes and concentrate the best thing you can do to raise your test scores is to pay attention when you're supposed to be learning the material: in class!

take good notes.

do your homework.

use mnemonics and other tricks.

do practice tests.

call the larger triangle abc

then the smaller triangle cde is similar to abc (all angles are equal, aaa).  

ab is the side that is 36, and we wish to find de, the side corresponding to ab

area_cde = area_abc - area_cde --> area_abc / area_cde = 2

let x=length of de

ratio of areas = (ratio of sides)^2

+2+=+1296%2fx%5e2+

++x%5e2+=+1296%2f2+=+648+
