comment Proving measure of set is $0$
How are X and A defined? (I Assume X is a set on which the measure is defined and A a subset?)

comment Finding moment generating function from piecewise CDF
The facts that $F(x)$ is zero for values smaller than $1$ and $\frac{1}{2}$ at $1$ imply the point mass. Where the cdf is differentiable the pdf is the derivative of the cdf. At 1 however, $F(x)$ ist not differentiable, as it has a "jump".

comment Need help with statistics homework
Do you have any information on the assumed distribution of outstanding balances? Without that you cannot calculate anything.

comment For what $f(n)$ does $O(f(n) \log n)=O(\log\log n)$?
Are we even considering decreasing functions?

As far as I know there is no "slowest growing function" (apart from constants) as you can always take the log of it and make it even slower. Or take the inverse Ackermann and apply itself again, then log, then inverse Ackermann... it always gets slower and slower. But this does not solve the original problem.
