Thank you for posting. They are really helpful.
One thing from this post:
Why x is from t^2 <x < t^2?
I don't understand.

michiko75,

If we square both side of
the inequality x^1/2 < t < 2x^1/2
we get x < t^2 < 4x , which can then be
written as t^2 / 4 < x < t^2 .

Shouldn't it be limit instead of deductible on page 2?

michiko75,

There is no deductible in the solution.

WIth a policy limit of 1, the insurer pays 0
if the loss is 0 and the insurer pays 1 if the
loss is >= 1, so the expected insurance payment
is P(X>=1) . Similar reasoning applies to the
policy with a limit of 2.

Your wording in the solution says "The expected insurance payment on a policy with a deductible of 2 is..." perhaps you meant policy limit

Actuarialsuck,

So it does. I can't even read my own writing
when it is typed out. The solution should read
"policy limit of 2" rather than "deductible of 2".

Thank you for pointing that out. I will post a
correction.
