comment Enumerate solution of $x_{1} + x_{2} + … + x_{r} = n$
There must be some restrictions on domain. otherwise you have infinitely many solutions.

comment Combinatorics/Permuation question - Am I overcounting? (Verify my answer)
The Q seems to asking for "at most 2 repetitions of a digit". That's any number of digits repeating, but repeating at most twice. 11220045456 is a valid answer, but that's not what your solution is answering.

Depends. Check whether 1-(5/6)^3 is "probable".

comment Problem with slopes.
Negative slope means the curve is moving in opposite directions on x- and y-axes -- towards negative on y-axis while the value on x-axis increases. A negative number is negative, doesn't matter where the '-' sign is.

probably not worked. but it doesn't seem as hard as the lower bound which is solved in part.
